so i've finally gotten this underway again. i had a hell of a time with collision and response between squares/rects and tilemaps. there was always something not quite right. thankfully x-out in #ludumdare gave me the tip i needed to get out of my bind.

i don't have any screens worth showing yet, but i do have a bit of the controls and fortress interaction on the go. you can fly around and into fortresses, you can bounce off the walls and stick to them, and shoot them. i've got a slew of things i want to implement still, but most of the player input is in.

i'll post as i make leaps forward.
