This entire thing rocks (hehe) conceptually. I am NOT good at rhythm games so I was pretty worried about my ability to play this, and I can't multitask this sort of thing very well, but the arrows were very forgiving and had a lot of space which made it much easier to actually feel how the game could play.
The arrows stand out so much against the background it made it easier at a point to focus more on moving and having an approximate idea of which order the arrows were coming in, the actual movement is fluid and navigation is easy as a result. I wish the default attack had a slightly wider radius and the enemies had just a little more feedback when they died.
Very interesting game, awesome concept, best music choice, all around fun and good job within the time frame!
