Earth Prime

by Satyre - Jam Entry

After the Big Bang you are responsible for the wealth of the planet Earth. Choose your upgrades to lead mankind to glory by increasing productivity, technology and population to the max, while reducing the pollution to a minimum. Be the fastest strategist and discover the truth about your planet.

You play the game with the mouse only and choose your upgrades.

Important: Every upgrade costs 5% of your productivity,

It was made with Stencyl 3.0, Photoshop CS3 and Fruity Loops 9 for the Jam in 12 hours.

Enjoy saving the planet ;)


The theme in this game is to think about a way to save your planet, cause there is no way in real life to simulate the influences of pollution perfectly, so you only have one chance to save it, otherwise you / we all lose ;)


Thanks for all your Feedback so far, you are great!

Play the Newgrounds version to see the changes of your feedback.

Can't the the theme here. Graphics are nice. Clicked on the buttons a lot but nothing happens.

population keeps growing by 0.128, no matter what the multiplier is.

Hey thanks for the feedback. The theme in this case was meant to be one earth, where get one chance to save the planet. For the conrtols, I couldnt create a better help and visual feedback in that short time, but you can click or upgrade only when your resource (productivity) is higher than 5%.

Very creative idea, but as far as implementation goes I have no idea how to play. I can see you control things with the mouse, but I don't seem to get any feedback from pressing anything. I'm just a bit confused how the game plays.

test sucessful completed in 123 s, nice! :)

Cool game. Wasn't really that fun in the end though. Very numbery.

So I think I beat the game "Test succesful in 69 seconds?" It caught me by surprise :P - Apart from that, I liked the idea, simple, and although not very well explained, I understood the concept fairly fast. The graphics was very nice, and I liked your intro.

Interesting idea, but a tutorial? As a general rule I love this kind of game :) Nice graphics for the earth by the way! :)

Nice idea! I like the graphics and the music.
After winning, I realized, there was a help screen :D I think it is quite intuitive, though.
Some more options and a longer duration would have been nice.
Cool game ;)

I beat the game, but only worked out how the mechanics work by reading the comments.

I think that its not about this theme, but overall it's a nice game!thank you!

Tough one to judge: I really like the graphics and music, but due to the lack of feedback (even just graying out buttons would have helped) I don't really feel like I have an influence on whats happening.

Lovely! Though I wasn't particularly swift, I did it without pollution. I would have opted for leading zeros (and trailing after the dot) for all the values so that the text stays in place.

ThatGuy says ...
Dec 17, 2013 @ 6:05pm

Fun gameplay and concept. Pollution and population seem to randomly drop to 0 sometimes, and population doesn't seem to be important for the win condition, only tech. 62 seconds! Good game!

Nice game, but I didn't feel like I the buttons I pressed had much impact. Won it by pressing the technology button repeatedly. However, I like the idea and I think with a bit more polish on the mechanics this could be a nice game. I really like the graphics and I how the earth changes when you get more technology.

Where is the source?

HellBlazer says ...
Dec 17, 2013 @ 6:51pm

Nice concept, though it's a bit limited as it stands now. It seems like all you have to do is take technology as the first upgrade, then pollution drops to 0 and never increases again. More feedback in the UI would have been nice too, it's confusing at first.

It was a nice idea.

Had to read the description below the game to understand the mechanics. A bit distant from the theme. Nice Soundtrack, interesting graphics, but the interface needs to be more responsive.

Gamelabbers says ...
Dec 17, 2013 @ 6:58pm

I saved the world! Music is very nice and ambient, could do with a little bit more variation... although for 12 hours, pretty impressive :D user interface is very clear, and the help function got me to scratch my head (in a good way!) You know... trying to fight the urge to bash buttons at random till I win, very nice.

Great tech here. Gameplay is not engaging, but I think you have a winning idea here, there's not enough Sim Earth games out there.So keep working for a postcompo build with better gameplay. You must think about action and feedback, you press a button, something happens SNAP, out loud. Maybe you can use the idea of build monoliths or other divine items like UFOs, arks, that influence the population. Population should grow automatically, so technology and pollution, but with those items the scientist would influence the destiny of earth indirectly.

I like the concept, but it's not really fun or interesting enough to keep you in there - maybe either make the multipliers bigger (so game progresses faster) or have a bit more that you can put input into?

It looks nice, I liked the effects for zooming in and out on the earth. Like a few others said I found it a bit unclear; the first game I just tapped technology up a few times and won in a few seconds, but the second time I couldn't get anything to happen.

Unept says ...
Dec 17, 2013 @ 9:31pm

Pretty great job for 12 hours! I would consider adding more visual feedback so players know what happens when they click, stuff like that.

While not exactly fitting with the jam, the graphics and music are amazingly well done and the gameplay is very straight forward with a bit of strategy added in. Brilliant job!

Would have been great if we could compare our score to the score of other players.

Interesting idea, it's rather fun :)
It reminds me of one of my old games, except better! Sweet-as bro!

Awesome music. More instructions would be better I guess.

When I get the mechanics right I really enjoyed this game. Yet it still a little bit short for me but still cool. Music is great and moody. :)

Nice music.

Spammed tech+ and got success after 70s, so not that much to the gameplay. Seeing the planet change was a nice touch.

Shigor says ...
Dec 19, 2013 @ 12:07am

Not much of a gameplay, too simplistic and easy (after realizing what I'm doing, it would be nice to give some negative feedback when you can't push the button).
Full power to the audio!

Nice idea!

Diptoman says ...

The subtle changes in the planet and the moon were nice, and the soundtrack's great!
I couldn't see any use for population, though. Kept spamming production and then technology, got 63s.

What a really cool idea! Simple yet effective. My first game I was trying to understand what to do... didn't read the help. was successful in 164s. I read the help, played again and won in 60s.

Gungnir says ...
Dec 20, 2013 @ 5:39pm

Nice idea for the theme. Could have used more feedback on button presses - as you know, and piling everything into tech seemed to work okay.

Erkberg says ...
Dec 20, 2013 @ 9:55pm

A nice game, but those buttons really need some feedback. Good graphics and audio!

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.
