I took 3 hits (after a few retries).
The music is pretty good and I love the way it stops when you die. The game is fun and dynamic, it feels very good, the patterns are cool and the speed of the game is appropriate, you really want it to be fast and eventually get super fast and it does exactly that. The fact it switches halfway between two different things (continuous and grid) makes it even more dynamic.
Very cool game, looking for additional songs.
