I have a question. It seems that 'A' is based on "key pressed"... while 'S', 'D', 'J', and 'K' are based on "key released" (I'm not sure about 'L' because I rarely get that far). Is it supposed to be like that? It's actually much harder trying to release the buttons on beat, since it requires instinctively holding them down before the cues, and I can't hold down five keys at the same time because of my laptop keyboard's low key buffer.
It's a real shame. Even though the game does seem quite hard on its own, the strange control reading is quite frustrating as someone who has played rhythm games before. The art and concept is cute, and the song is a pretty cool MIDI.
The audio is a bit loud; it regularly peaks at or above +0.0 dB.
Congratulations on the submission!
