Drat...
Well, I won't have a game done for this Ludum either! I keep doing this. :)
My problem was that I had a very big arcade expo this weekend, so my Friday and Saturday were mostly taken up with that. It only left me Sunday and today to get something going.
I then made a mistake of trying to use a framework which didn't support rotating tilemaps to make a game centered exclusively around rotating tilemaps. I was able to hack in support but it was just going to take too much time to modify the physics engine to handle that.
So I switched to Unity, but this also had its own problems! I needed to write my own Tiled map loader, because my friend requested that he have the ability to create his own levels. So I couldn't use any existing solutions (as they aren't geared for this, due to heavily pre-processing the TMXs before they are even part of the Unity asset resources). Ergo I spent most of my Sunday just writing that.
I have a working concept but you can't even shoot at anything. Not that there is anything to shoot at... :pig_nose:
Anyway, what I have:

Want to guess what game I am playing homage to?
