This is a perfect game for this game jam. The controls are great, the visuals, the gameplay, are fun and work great! But what I really appreciate is how you used stereo audio to predict incoming attacks. Its such a nice touch and lets the game be appreciated from up close without making it unfair.
Honestly, if you just explain the controls as part of the game (you did a good job explaining it in the itch page), no one would even think it was a game jam game.
