doesn't it indicate how much value it has? cause usually when i upgrade a building enough the trash changes color.
also i think the minigames are neat, even though they dont really do anything, so nice job on those.
The trash gets more colorful depending on it's value (how much money it gives). But the actual color only depends on where the trash was generated.
There's a lot of people that played the game and you're the first one that commented on the minigame! :) They'll have a more important use in the full version.
