Great game! I had a blast playing it to the end. I really liked the VS style combat system, very effective. It got a bit too easy after the first fight (I only upgraded damage, fire rate and bullet speed), but it's better that way for a jam game. I would have loved to have a final boss fight, maybe not the chicken since it helped a lot, but for the time frame, this is extremely polished and just the right length.
Congrats!
