I'm trying out as many games as I can-- this game is and was a barrier to that because it's SO addicting.. You made something really great here. I love the music, it loops really well. The art style is really good, the game is intuitive to learn. Only change I would make is to let you know what the adjacency bonuses are for buildings before you buy one, so you can place them to benefit from bonuses without already having one down. I also think it falls a little short on the theme of "Erase", but I'm not at all upset about that. This is an excellent idle game!
Love this, A+ work.
