Comes with a demo level.

Changes:

Added a test level: just an island with long-ranged and short-ranged defenses.
>Short-ranged defenses have a good bit of knockback. Try circling the outside
of the island to snipe all of them. 20 HP, 5 shots/sec, 0.05 damage
>The long-ranged defense cannot be outranged, but lacks target prediction. Just
keep moving and try to stay perpendicular to it. 40 HP, 1 shot/2.5 sec, 1 damage

Cannons (2 HP each) and the bridge (5 HP)can now take damage, though I
havent added any part responsible for the ships movement (like a propeller the
ship moves much slower if destroyed or a rudder the ship turns much slower if
destroyed).

A little WIP color select feature. Try changing the color of the box.

Loads of small changes to ship's shells.
