Got some solid work done this afternoon. I have enemy ships automatically spawning off-screen, and tracking into the playable area. They will currently randomly wander, stopping to shuffle about for a bit before picking a new way-point. They have the ability to fire upon the player, but not the intelligence to track the player for a good shot. I'll have them preemptively slide forward/backward to put them into a firing position if they 'see' the player is near them.
Long-range shots are colored differently, with a purple aura, and hit harder. Firing direction is determined by the last direction you moved in. This seems lazy, but I was concerned with having 3 or 4 buttons for firing control, and that really seems a bit much. Doing this reduces it to two buttons: one for short range, the other for long range. I haven't had any difficulties snapping off shots in my testing this evening.
With tomorrow, and two more weekends before the end of the compo, I need to have more days like today
