I love the idea of killing monsters with rhythm!
Unfortunately the attacks and moves are a little hard to pull off because I'm either doing it wrong or the inputs get rejected even though I'm nearly sure I'm pressing the keys when the white border appears (or just beforehand, maybe that throws it off?). I'd love if the leniency window was wider here and maybe even make three tiers (good input = symbol added, okay-ish input = input rejected BUT the symbols you've already put in don't vanish, complete miss = all symbols are gone like right now when you miss). It probably doesn't help that I don't really feel the synchronization of the input windows and the music, but that might be just me. Overall it felt a bit frustrating and I didn't get too far in this game :(
I'd love if the game told you straight that you need to check the pause menu to see which combinations you can do.
Another gameplay idea I'd love to see is the shield blocking your attacks completely. Currently they only seem to reduce the amount of damage, so you still might be killed even if you summon the shield as a last resort?
I like how the game looks overall, though! Love the symbols and the zombie sprite looks really polished!
Thank you for fixing the HUD rendered behind trees by the way!
