Stop global warming

I made this game for the IGA Impact Jam but I had only the saterday free to work on it on the whole weekend.

Game : 

You are on a planet that has a lot of problems with global warming so you need to find a balance between planting trees and building houses. The houses release CO₂ (in the web version of the game it shows CO instead of CO₂) while the trees absorb it.

Controls : 

You can play this game completely with your mouse : the right click moves the character, the scrollwheel switches between house and tree and the left click places a house or a tree. You can also use '1' to select the tree and '2' for the house.

If you have some suggestions or see a bug feel free to share it in the comments.

Here you can find one of my other games.
