Love the game! Really cool concept, and would be down to see it as a full game!
My biggest frustration is dealing with the fire ants and the enemies further. Mainly because the parry system really messed me up for not being as good at it. However, the game sort of changed with the fire ants causing me to realize that I could attack/parry/attack during one of the fire ants attacks making it feel like a strange use of movement to approach enemies in a different way.
As someone who plays a lot of rhythm games, this game was actually really hard because of some of the attacks, target prioritizing, and playing really defensive. To me, it really feels like the dark souls of rhythm game in a way (idk if i can compare mechanically to armored core, i never played it)
