Pretty cool, I guess this would count as a roguelike. The deflection mechanic it fun, but the game is kind of cruel. Maybe some safe zones between rooms, or only drawing easier rooms starting out would help with the difficulty curve. Also, I feel like if the enemies each only took one hit to take down, the pacing would be better, instead of me just spamming deflect as they continue to shot and not being willing to take risks.
Besides that, well done. Certainly one of the more "playable" entries I've seen so far!
