I want to compliment you on this game, It's well thought out, (the visual novel at least :D) at times you have very strong literature elements, and others, not so much. Aside from that I really enjoyed it 5 stars and faved.
A great thing to do, which is pretty easy, is when the mouse hovers over a button make it highlighted and make it dilate in size when its clicked, makes it look a lot better.
Great game so far, i love the intricate upgrade system. Bug: when your armadillo falls at a really fast speed and hits the spring, it cancels and you lose a lot of speed.
