Stopped working for the day a while ago. Including the idea stage early this morning (5am local time) I’ve been working about 18 hours today minus lunch, dinner and some shorter breaks here and there. The game is coming along nicely but I’m getting a bit worried I won’t have time to add everything I’d like to. That’s to be expected I suppose. Today I managed to complete the screen/menu system, movement and controls as well as my “ping” based visibility system and accompanying sound and visual effects. Here it is in action:

Enemy ship spotted!

Enemy pinging just outside our ping wave, revealing its position with a small visual effect.
The main task for tomorrow is to get the combat going. I’ll probably use missiles; area detonation for shooting stuff you can’t see and homing missiles for visible targets. Levels will just be an increasing number of random enemies, or I’ll simply spawn enemies in waves as they get killed. I have at least 2 different AI’s planned and the simplest one is basically done apart from the shooting. Another thing I’d like to get done asap is some nicer background than a flat black.
Maybe I’ll actually get something submittable done before the deadline.
