Music and graphics are wonderful, nice job on these. But I think it is too hard, enemies are so fast and it takes a lot to finish a room. But the idea is very original, instead of you rewiniding, the enemies does. So points for you! It is a cool game with a nice story, but if you add more things and adjust a few things, the game would be great!
Nice job on the game! Be sure to check my game too!
