I was rather impressed by this. I was afraid it would be a game where you had to avoid everything on the sides, but it was not. I'm really intrigued onto how it works. You can can't a good part of the screen because of the menu on the side. I hope that's part of the game and not a glitch. Whenever you hit something, you really richocheted off.
I was impressed at how well the game tested your patience. Going fast was pretty much always bad. The graphics may be simple, but it's still challenging. I like how that creates a sort of conflict with itself. It's, in my opinion, a very underrated game.
