I had absolutely no clue what was going on, but I loved every moment.
The damage and wedge system really didn't click with me, and I never quite got how it worked - but the sound and visual art design was great, and it certainly felt fun to play.
I think more clearer metrics and visuals for how good/bad you're doing, combined with some better options for strategizing, would be best.
The soundtrack takes the same beats as the sound effects - and it worked really well, not feeling too over-the-top or too tired at any point. I think with the right gameplay polish and clarity this could really shine.
