This game is incredible! The art style and calming music strangely reminds me of Animal Crossing City Folk. It's fun hearing tunes I recognize. The pixel art is stunning, I feel the care that went in. A tutorial?? Like a GOOD tutorial? for a JAM game??? I love the little touches, too, like the grid system for when you jump, go to stab, and you get "snapped" to the grid so that it's obvious which tile you are hitting. Even with having to avoid a few bullets, this game is so relaxing.
I noticed it seems you can immediately stab again after getting a successful stab, this may open up some opportunites for speedrunning :) Although how feasible that is, I guess, would depend on whether the songs/maps are randomized.
Anyway, my final thoughts: I can't believe this is a game jam game. My only suggestion, the notes that play when you stab could harmonize with the background music... That would probably take a ton of work though. The polish is unreal and I hope it grows immensely in popularity! I'm going to go finish playing now :)
Edit: As I play more, one other thing I think might help with play-ability/accessibility, make the tile you are currently standing on/over top of highlight a slightly different shade, this would give a subconscious sense that you know exactly which tile you are targeting instead of feeling like you are taking a guess.
