Not only is it an AMAZING game for a game jam, it is an AMAZING game in general.
I don't know how you managed to create a system to make that bullets sync to the music in just a weekend, but you doing that (or syncing it manually) made this game CRAZY GOOD.
Took me 3 tries to finish it, and I loved every second. If you make this a full game, I would love to buy it!
