Quite a cool game! The story seems intriguing, although it wasn't fully fleshed out (but that's to be expected in a game jam).
I have two personal suggestions for the gameplay:
- I would add a cooldown for the attack to prevent spamming.
- I would prefer if you switched lanes adjacently (i.e., from the left lane, pressing right would only move you to the middle lane). I do understand, however, that the current controls offer more direct control.
Nice game overall, well done!
