I really liked the art! The SFX also worked really well. The movement controls were pretty good, but I agree with other comments that clicking to shoot was awkward. I would have liked more audio/visual feedback for when I was at risk of losing, too. Still, this was fun and had a really nice aesthetic. I'm impressed how many mechanics are at play and how smooth it ran for just starting to program your first games in the last couple of months.
Great work on your first GWJ submission!
