I like the game overall, but it is still too unbalanced. The character is so weaker thann the enemies that it goes to the level of the ridiculous as I lost 3 hours to kill the first boss.
Every game in that style is off-sync with the song, it's unavoidable. As for the game not registering 3 notes at the same time is because of most keyboards in most computers.
I personally addore this game.
Another protip: If you pause the game every time the Gen is going to make a move, you can avoid all of his attacks, including the "unavoidable" insta-kill.
Plus me if you took advantage of this comment.
The deathmatch status are awesome. However, it would be more awesome if the game allowed the players to:
1 - Have more custom map slots
2 - Had status only for the players
3 - Had the possibility to edit the premade maps
4 - Had the possibility to add custom hazards.
