Alright game. A little hard, but maybe it's just not my thing. The music is a little schizophrenic. It disturbs me that it changes so often. Stick with one style dammit!
What I did to beat the final boss was to basically turn my keyboard sideways and then just drum my fingers up and down the number line and the 'asdf' line. Still had over 3000 health when I finished.
Alright game. I don't like how you have to kep on switching from the puzzle to the fight to find the bottles, but other than that, it's all right. I absolutely love the contradiction between the night and day music.
