This game was a really surreal experience. The entrance to the game was really cool and I loved the matrixesque hallway leading to the multiplayer. The sounds you chose for the players made for some really cool dissonant and otherworldly audio and I loved the level design. I really enjoyed the experience.
When I clicked on the computer to enter in the username, I tried to back out of it to make sure I didn't miss anything in the room only to find that I couldn't leave the computer once on it. I'd also like to be able to press multiple notes at the same time.
