Had a lot of fun playing this game, even though my fingers hurt from the clicks I had to do in the blue mat (maybe increase 2 air for 1 click?). I played uptil I got $12 and didn't continue after that. I think the pacing should been a bit easier, i.e. the first achievement should be $5 or $10, after which a new element is added to the game.
Good job with the voxel art, gameplay, and nice (mis-)interpretation of the theme. ;)
Keep making games!
