Arrow keys move the diver. Don't get eaten by sharks. Your goal is to get the treasure and get back to the surface within the time limit.
Please read all of the notes and credits. Thank you! Thanks to my dad for support. For difficulty suggestions, they are as follows: Easy: 1 shark, 90 seconds. Medium: 2-3 sharks, 60 seconds. Hard: 5 sharks, 30 seconds. Enjoy!
