Really ambitious game ideas here, I'm fond of the overall mood and scope. Reaction time based enemy encounters is a great idea - it might be my emulator (gambatte) but every single time I tried to hit while the cursor went up, it was a miss, no matter how I felt about it - every time the cursor traveled down, it was a '!!', which I think is close? (I would contest all of them were hits).
Extremely cool atmosphere, I'm happy to have played it.
