Really amazing presentation and music !
I also really like the fact that you made a level select in the menu to be able to see more than level 1 if beaten down by the difficulty :p
One thing i was a bit confused about though is the rhytm aspect, it seems obvious from how the enemy attacks and all seem to sync to the music’s beat, but the parry and shooting didn’t seem to work like that ? some shots had really slow firerates while other seem to shoot fast for a given time or ammo count ?
Now this confusion aside i still really like it, the spritework is really cool, i dig the cyberspace kind of setting with the scrolling grid backgrounds, and the music like i said is awesome !
Well done :)
