Use the arrow keys to control your damaged sub. Press space to turn on the grabber, which you use to pick up treasure. Bring them to the net. Be careful not to get the sub stuck at the sides. The sub is gravitational. Because it's damaged, you'll only be able to move the treasure a little way at a time. At first you'll start with the Practice Cave level where you bring the treasure chest up. Then you can move onto the real Coin Seas level!
Please comment and love. A new project is coming out soon! If after the sub finishes the instructions the sub does not move off the platform, click the green flag again and it should leave the platform the next time.
