The game’s visuals and sound design are really well done, and combined with its unique concept, it definitely stands out. Especially since there aren’t many rhythm games in this jam.
However, as someone who’s played quite a few rhythm games, I think the note key layout could be improved. Usually, rhythm games use four directional keys (like the arrow keys or WASD), which feel more natural to press. In your game, the notes are mapped horizontally (J, K, L, ;), which works better for finger touch-based rhythm games, like piano-style mobile games.
But on a keyboard, this layout makes the game unnecessarily difficult. You could technically play using both hands to balance it out, but since you also added extra keys on the left side, it becomes even more frustratingly difficult. Not because of the notes or timing (which is the fun part of rhythm games), but because of the awkward control design itself.
I’m sorry if I’m being too direct, but I really just want this game to be fun for everyone. Even for those who aren’t very familiar with this genre.
