Thank you for taking the time to write such a detailed feedback. Much appreciated.
Here are some things on my "if I have time left i will implement"-list:
- rotate the character when diving up- and down
- Fish getting tangled up again when hit by garbage
- way less oxygen but a refill station
- sound effects / victory music for freeing sea creatures
- more skins for garbage and sea creatures
- underwater scooters for brief speed boosts
- fix the hole next to the trash can rock
- more levels
- animated bag with fill progress bar
- Improve delivery animation
- Display message when you're in interaction reach with fish/garbage/trash can
- SHARKS
- learn how to properly skeleton-rig the main character
Now, I probably won't have the motivation to do all this when the jam is over
