Such a cool game! The concept is simple but good, and insanely well executed! The graphics are really good, and the game is very polished.
It took me a while to figure out that I could use other buttons than just E, but that's just me not being smart.
The one thing isthe audio, which isn't bad, but it feel like it could use a little music or some more different sound effects. But that's not a major complaint.
