thedaian says ...

Neat idea, and a pretty fun game. Too bad it's silent, and it becomes really easy to clean up the oil once you get one or two bonus buoys. Still, I like what you did.

pekuja says ...

I really liked this game. I wish it had some more variety in levels (yeah, minimalist, I know), and some music/sound. The environmental theme is nice. I didn't really find much use for the nitros, although I guess they provided something else to do other than decontaminating the oil. The speed boost wasn't all that useful though.
Good journaling effort.

NULL says ...

Nice! It's a pretty fun game. I like the idea!

Hamumu says ...

Wait, N is for nitro? How do I nitro? I thought those might be bits of net. Where are you people getting more information?

I didn't understand level mode at all, especially when I finally got all the Ns and it sent me to a blank blue screen with no boat.

But in the number modes, it worked great! I love those kind of pushy physics, and wrapping stuff up is always fun too. It was super easy (I guess it couldn't not be, what with no lose condition), but fun to control. I liked how to motor swung too.

dgriff says ...

I liked it, more polished than most games and pretty fun. The oil blobs were fun to splash around in.

mikeware says ...

Really fun game, great achievement for 48 hours. Too bad there wasn't any sound though, that would have just been the icing on the cake.

HybridMind says ...

Pretty cool game. Really fits theme well I think. Like others have said, miss the sound but I just made burbling outboard motor noises in my head.. ;)

Nice touch with the motor counter rotating with the turns! Wish it had a timed mode to add to the challenge as it is a bit too easy otherwise. Great for what it is in 48hrs though!

Devon says ...

ah so free mode has no oil. ill try it again if I can get out of free mode.

DrPetter says ...

Impressive polish and smoothness. I'm curious as to how you did the whole loop-fill thing when wrapping up oil blobs. Can't see an obvious way of solving that, unless maybe the playing field is divided into a rectangular grid and you sort of floodfill the outline made by the divider... but then you still have to find out which side to fill. I did some stuff with concave polygon triangulation a while ago and it was pretty nasty stuff, but I guess that could also be a way to do it. Suppose the answer is in your code, might look some day.
The controls and everything else turned out real nice in the final version, but it's still pretty lacking in gameplay and challenge. Might have to throw in some "enemies" or other obstacles to create challenge.

Wiering says ...

I played it for a while and it was fun, a bit too easy, but the physics are nice. At first I though the level was unsolvable because one "N" was completely unreachable (in the middle of an island), but in the end I got it by surrounding it with nets. The blue screen after completing a level was kind of disappointing though.

keeyai says ...

Nice! I really liked it. I avoided the nitro until the end though, since it was more of a hindrance than a boon. Annoying that you HAD to get them to finish the level, but no big deal. Overall it was really great. Also -- you are a brave man to let those little girls eat right next to your running laptop. I would have given you a trophy for that if the picture worked well at 64x64.

philhassey says ...

Pretty fun one. Some music + sound would have kept my interest longer I think. Pretty good innovation I think.

mariusz says ...

Even running the stand-alone Windows version, I can't start the levels. I just get free mode instead. Eventually I got it working on Linux in a browser, but it was slow. I like the idea and the game is pleasant enough, but it got boring after a while.

erik says ...

Cool idea and mechanics. I didn't feel challenged though.

Dathgale says ...

I like the concept, but the game is kind of tedious. Without a lose condition it's more of a "toy" than a game, much like SimCity. I like the artwork. It reminds me of Abstract Sea (http://crazymonkeygames.com/Abstract-Sea.html).

phren says ...

Cool idea and gameplay. Was a bit boring after the dust settled. The graphical style was quite nice. I didn't seem to get into level mode, for some reason. The islands in the middle of oil spills kinda threw me off, too. Overall a pretty good package anyways. :)

robot_guy says ...

Great fun but it's a needs to be a bit harder, a time limit might have been good.

gustav says ...

Very cool game, fits the theme well and it has awesome graphics :)

I have not been able to run level mode though, and the difficulty in freemode doesn't increase or put pressure on you to hurry up. Other than that, it's a very good and polished game! Good work :)

EDIT: I played the browser version and levelmode works! I really like how the instructions float in the sea and the levels made it more intresting to progress :)

jolle says ...

OK I'm done saving the world seas now. At one point I thought it was a trap, but turned out the trap was nothing but lies!

Nice look, nice idea, fairly fun, but lacking something in gameiness.

pansapiens says ...

Wonderful game, good fun, quite innovative. Like others have mentioned, some audio would be nice. I love the little touches like the way the outboard engine moves independently to the boat.

SethR says ...

Great level design, especially liked how the little outboard motor rotated correctly when turning, nice touch. :)

negativegeforce says ...

real nice idea. i bet you could do well on advertising dollar for this game on flash sites.

Exxon on Vista (Perhaps other systems aswell)

It’s a trap

I’ve found out that level mode is troublesome on Vista system. Running my game in a browser solved that problem. However, performance goes down a lot in the browser. To get decent framerate shrink the browser window until it feels good. Here is the game

Same as the exe but online.

Exxon – The decontaminator

Exxon - The decontaminator

You are on a mission, decontaminate that oil! Instructions are in game. The name Exxon comes from a oils spill disaster in the USA.

Download in following flavours:

Flash 0.2MB – Requires Flash 9 installed
Windows Executable 1.5MB
Macintosh Executable 3.9MB

Running the game in a browser is possible, but cripples the framerate. I recommend running the executables or running the swf in flash player 9 not in a browser.

Exxon - The decontaminator


There are two modes: Level mode and Free mode. Click: “Click to play” for level mode. And 600,1200 or 2400 for Free mode, where the numbers are how many oil spills there are. Note, if you by any chance run the game in the browser, the Level mode might not work and falls back to Free mode 600. If you see a lot of (N)’s around, you are in free mode. Go back (Esc) and click “Click to play” again for Level mode. (Xml loading issue)

Edit2: Those on Vista could not run the game in level mode. It turns out that running it in a browser worked. http://enedahl.com/ld11/final/exxon.swf
Same as the exe but online, will hurt perfomance though… keep the window small for better fps.

Island in the strea… breakfast, day 2

Ahhh that coffee was great!

Islands are temporary up, No collision responses yet and uglyishly(I made up that word just now), randomly placed. I made all islands fit a circle, to simplify the collisions a lot, fits the theme as well. I’m gonna put the islands in a separate sector manager. Next is collisions and neatly placed islands.

Decontaminate that oil!

To be decontaminated

Closing the gap!


Ta da! The oil is gone! It’s magic!

Want to test download the exe (windows) or run the swf, although the swf is slower. Arrow keys to drive, space to deploy buoys.

That’s all for day one. I’m going to bed. (00:13)

Hotdog with buoy action!

Bouy frenzy

Crazy buoys flying all over the place. I got them under control now though. Next step is to close the buoy divider and get points for decontaminated oil spills.

Strange bread

Hotdogs! Yeah, I forgot to buy the bread. Toast it is. Works.

Oil spill

Oil spill

Great, I had a tough bug haunting me for some time. When it finally was fixed I got the game up to speed. I can have 2000 oil spills at good framerate in flash on my laptop 2ghz centrino. Thanks to some dynamic sectoring.

Next up is to wrap the oil spills by dividers that will be dragged by the boat. And then some islands.

Oil and eggs

Oil and eggs

Mmm chocolate eggs.

On the screen you can see 200 oil spills (circles) pushing each other away to a distance, thats about the maximum amount possible ATM. I’m investigating dynamic sectors to solve the performance issue. The oil is moving slow so they don’t need to update their sector every frame. perhaps once every two seconds.

Ahhh nice weather

In my garden. It’s really not much bigger that what you can see here.

A closeup

Mmm Sweat and sour chicken.

Thinking about my game, the boat is steering now. Could use a little tweaking, but I’ll move on anyways, not to get cought up in tiny issues. Not putting up a screen now, think title screen with only blue and boat and you got it.

Ahhh the coffe is ready… back to coding.

Exxon - The decontaminator - Title Screen

A sketch of the title screen.

This will be a 2d topdown boat game in flash. Isolate oil spills with dividers. All graphics and sound are kept minimalistic and simple. If stuff goes quick and I have a playable semicomplete game today I will try make it multiplayer.

The name Exxon comes from a oils spill disaster in the USA.

Breakfast with the family

Me and my two chidren, eating at my workplace.

Coffe and a sandwich

Coffe and sandwich

Energy topping

Some energizing topping..

And the idéa for minimalist?  Perhaps a boatgame I had in mind before the compo. Yes, I’ll elaborate on that idéa. The minimalist part will be the visualisation of the game, both graphics and sound. Clean, simple.

I’m sitting in the kitchen this time. With my laptop. The stationary PC’s monitor is blurry and I cannot look at it more than half an hour or so. Whats up with the toys? Well… I got kids. Oh you mean the Nintendo DS? Thats mine ;P


Want a closer look at the screen? I’ve begun brainstorming on the themes with most votes, those on the left are less likely to win, and those with bold type got more than 10+ votes.
