Absolutely ADORABLE art, and I really appreciated the use of the shark fact in the theme!
This game is super hard, lol. I really enjoy bullet hell games so it was cool to see one in this jam! I think I've encountered a bug that the "shoot teeth" option only happens some of the time and takes a long time for it to happen at all - unless that's part of the difficulty? Also, you have to stop to be able to move upwards. Those are my only suggestions on this.
Considering the time constraints and this being your first Godot game, you did very well! Good luck and happy jamming! :D
