Brave Island Diver is jwaap's Ludum Dare 17 submission, a platformer where you're tasked with collecting all twenty-five stars placed on both above and under a cluster of islands. This requires jumping off a cliff, then gaining enough vertical momentum to reach a platform at the same height on the other side of the body of water.

You can use the cursor keys to move around, press the x key to jump, or hit the space key to teleport to the position of the last collected star. The F4 function key is for switching between full screen and windowed mode. (Windows, 2.36MB)
