Fort Apocalypse has released a new A2600 homebrew game called Waterskier.

Release notes:

version 0.2 – fully functioning game where you try to pick up “cans” in the water (or air). Thought this would be less boring than slalom. 4 levels: freshwater, seawater, night, and blood. Open to suggestions. I want to add a minigame where you have to avoid snapping shark while getting back in the boat when you fall (but you can’t fall in current game).
