Control the submarine through the ocean and get as deep as you can without breaking your submarine or running out of oxygen!

Collect samples to make money, use that money to replenish your oxy supply

Use lmb to cast your hook, try to hook onto as many things as you can, if something is too heavy and gets stuck, use rmb to unhook from it.

How you insta deliver oxygen to the bottom of the ocean? idk
but its lame jam so who cares!
