Operation Barrage

by sirdorius - Jam Entry

IMPORTANT: This game is designed to be played by 2 people on a tablet in realtime mode. Any other playing scenario (ie. PC or hotseat mode) is for testing only! Please consider this when judging and commenting on the game.

Manage gun platforms on your side of the screen to overcome the enemy's side. Your commander mines the asteroid and generates money, which you can spend to buy new platforms. You'll have to move and rotate the platforms and use their special abilities to destroy the enemy commander.

*TAP on a unit to select it
*DRAG your finger on the board to move your selected unit
*DRAG a unit to change its direction
*Tap the buy button to see available units
*Drag a unit onto the field to produce it (you need to have enough resources)
*You should only be moving units on your side of the screen. Try not to cover it with your hand uselessly
*On the PC 'TAPPING' is done with the left mouse button. You can also use the right mouse button to drag a unit
*You'll find instructions on what each gun platform does in the game tutorial.

Realtime mode is the way this is meant to be played. Unfortunately it requires you play it with a friend on an android tablet, so Hotseat mode is something I did so you can try the game on your PC using only one mouse, or maybe playing by yourself and have a bit of 'challenge'. In Hotseat mode each player has 5 seconds to make their moves after which they have to pass the input device to the other player (there is a 2 second pause between the moves in which neither player can move).

I didn't get the chance to play the game much, so if you have any suggestions on balancing units I would be happy to hear them!
Gamejolt, mirrors are coming soon. I really like how this game turned out so stay tuned for more updates.

* The commander is the unit with the star. It can mine the nearby asteroid (green) to get resources which can be used to buy more platforms. The asteroid moves around your field so you’ll have to decide if it’s worth risking the commander to mine it.
* The machine gun shoots bullets at regular intervals. It's a cheap and weak unit, but it has the potential to spam the enemy side
The shield blocks incoming attacks (will reflect them in the future, and will be disabled after a hit)
* The missle launcher shoots missles that follow the platform's rotation. You can micro these as guided shots that penetrate the enemy defense in tight points, as they do massive damage on a single hit. You can also use them to snipe the enemy commander.
* The mortar launcher lobs a bomb that will always hit the target and cause area damage, but is very slow to fire and travel and the platform is very vulnerable

I liked the minimalist style! please notify me when uploading.

Really nice game, though it took me a minute to really understand what to do! I Included it in part 1 of my Ludum Dare 31 compilation video series, if you would like to check it out :)

Tutorial is a little bit useless, I do not understand how to play. But I like your minimalistic style of graphics.

Nice, definitely better with touch controls though!

Nice. I can see this becoming pretty fun in actual playre vs player (i played solo). Graphics are ok, the only thing i would do differently - is make a background a lot lighter. This grey color doesnt fit too well.

Great job! It'll be much better with AI or networked multiplayer, but the potential's definitely there.

Nice game.

Nice idea! I had a similar one for a two players shared screen soccer game on tablets... (not for Ludum Dare though, this was before)

The only real complain would be the graphics, very simplicistic and not too pleasant, but the rest is very well made!

It's not intuitive to play and rather difficult to control the units on a touch screen. Especially for two player on one small tablet screen.

But it seems to be a nice game idea. There are way too few multiplayer games in here. So, overall I like it. It has potential. Well done.

I agree it is still too hard to control. I will be improving the touch and mouse controls in a post ludum version.

Neat! I only tried the hot seat mode, but I like the idea. Reminds me of a top-down version of Cannon Brawl.

it's a great work for 72 hours

Yes! I like local multiplayers on a tablet! Fine work for 72h. Great job!

awesome idea, looks like a really fun game. SOund is also amazing. Unfortunately controls are not correctly working on my fairphone ;( Maybe the screen is to small

Great, tower madness, it'll definitely be better with touch controls!

This would work well on a mobile device, especially if you could make it so two people could play at once on the same screen.

The biggest problem here is the lack of a single player - otherwise this looks like a fun game to play. Strangely, I got an odd satisfaction from attacking and defending myself; good job!

Well. I'm not sure about gamplay. But asteroids sounds attractive!

Hotseat mode switched back and forth so quickly that I had a tough time doing much in it, but real time mode seems really cool!

Nice concept, and well implemented gameplay. I do wonder about some UI choices, like putting the resources across the middle line and having the health of the commander specifically be kind of tiny and hard to see.

Well done! This seems like it'd be a blast on an actual touch device.

Extremely addicting!

I like the idea but it must be introduced in simpler way.

A single player mode would have been nice.

PORTS: Ports to other platforms can be done after the deadline.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
