I really like the Art and the Idea, for some reason I didn't hear any audio when I first played, but it was there after I reloaded the page. I really didn't get past the level that introduced the boost though, because I use the qwertz keyboard layout, so pressing shift and z at the same time isn't really easy for movement (I didn't dock any points for this though, because it isn't really an issue with the game), I think adding an option to change keybinds would be nice. Apart from that I really like the artstyle and it is polished quite nicely.
