While musical games are what reminds me of guitar hero, they didn't register keyboard strokes neither in Firefox, nor in Chrome. Should be fun to play, though, if they did.
No exit from minigames so had to restart page to quit. The wackamole is nice, good that you got it working, but visually unappealing. All in all, I think you should focus on the melodic games once reupload is allowed, and make a way to quit to the room.
