Ballast

Another peaceful day at sea. Your trustworthy submarine will take you deep into the ocean.

... That said, there used to be a full crew working here, but now it's just you.

Things can get chaotic quite quickly around here. 

Manual:

• If our submarine crashes we will take in water
• If the wheel is at max we will take in water
• Watch the TV if you want to
• If the pressure is at max the containers and the wheel will accelerate
• If one of the containers is full, the submarine will speed up

Good Luck!
