I only ended up getting one upgrade haha, but it was a fun little game. I would have liked more upgrade choices, but for the time constraint, great work! The music is fun and jaunty, gives it a great nautical theme. I hope you keep developing this and add more stuff to it! Actually my team created a slightly similar game, Hive Dive, but submitted incorrectly to the jam. Would love a review anyway, if you have the time.
