Hey, congratulations on submitting your game to this Game Jam! You did a great job.
I would improve the following
- Work on the balance/difficulty of your game: You can mostly "spawn kill" the crabs. Maybe they need to be faster, or spawn at a different position, have more health...
- Shoot a bullet when the mouse click is pressed and held. I find it not very nice to have to click to spawn :)
Hope you learned a lot during your jam!
