Very cool idea for a rhythm game. Once you get the hang of it, it's really fun! :D The two songs and their beatmaps are great. Especially loved how song 2 introduced some off-beat projectiles. Love the character designs (duh, who would have guessed >v<) and the pun of the game's name. ^^ The mix between 2D and 3D assets is an interesting choice. I would have loved to see you lean more into it but alas, it's a game jam and time is precious. ^^'
What I would improve is adding more sound cues relevant to what's happening in the game, like for example a special sound for projectiles that don't get parried right away and need multiple hits. This way you have audio confirmation of that as well and don't just need to rely purely on visuals. Other than that and the usual polish, I really think it's a pretty neat game. :D
