I love the game, super creative approach to the theme, like an opposite to a city builder, the humans are also so cute XD I think a good way to improve the game is a add more upgrades to combat humans, and for the humans to have more strategy to prevent you from building forests! All in all nice game and a very interesting concept!
If you can find the time, would you please check out our game as well?!
Our twist of the theme is that a critic tries to play your unfinished game, and you fight from inside the computer to make him like it.
