great game. every skin was a character from a game i played, beat, 100%'d, loved, etc.
music: epicness
graphics: retro epicness (reminds me of my zzt and mzx days)
gameplay: smooth responsive and fun
difficulty: incredibly easy. still rewarding for the experience. but i don't really think a game should be so easily 100%'d.
one complaint: when the game loses focus and you click back in to unpause, the click penetrates through and interacts with something in game.
