Player 1 holds 0 to fire/reload.

The AI isn't a real AI, and no scripting is used. It just adjusts its aim when you move. Of course, this is a beta, and the aim is thrown off sometimes. Sometimes it even fires at itself, but that usually only happens if you are stuck but hold down the arrow key...

This is a one player ship battle. Of course. And it has a breakable village in between the ships. But this one has a gun AND a mortar on each ship! The mortar is controlled using the same controls, but it is restricted so that it doesn't aim at your own mast .
THE CANNONS ARE MADE BY scrabs from his Gun and Puff scene. I modified them.
Anyway, the controls are arrow to aim/move and hold 0 (not on numpad) to fire and reload (reloads slowly). There are some breakable ragdolls that are cool but they lag sometimes. I recommend that you press u at the beginning if you are using a slow computer or a Mac (Phun seems to run faster on Windows computers with the same power as a Mac). That's not an insult. I am a devoted Mac user.
Try to destroy the other ship while protecting your own. The cannons reload slowly, so use your shots wisely. Player 1 holds 0 to fire/reload. If you are hit, you usually get minimal damage, but the next hit usually destroys your ship. The weakest points are the mast and the tip. Careful, damage to your mast may impair your movement. First to lose both guns or blow up loses.
