The unfortunate happened to me. About 20 hours in, I started to notice that something struck a heavy load in my game and made the frame rate drop ridiculously. Poking about in my code I found out that this flaw is somewhere in the rendering of my “engine”. I figured that I accidentally caused this when I tried to… urk, upgrade it. Beats me. “Don’t fix what isn’t broken.” fits so very well in this situation.
Half of the time has already passed, I am nowhere close to even have a solid idea for my game, I cannot even spawn 10 simple particles without causing the framerate to drop to 20 and I have already spent about 4 hours trying to find the bugger in the code. So for the first time since LD23, I am backing out.
I wish the best of luck to the rest of you!
