Hello, sorry for the delay, Ludum Dare ate up a lot of time.
Anyway - I loaded in the example demo (both versions of it) and let it run for a few minutes and memory usage stayed at a constant 11.58 mb. Hopefully the leak’s gone, but if it comes back send me the whole project and I’ll look around in it.
Also, 2.3.1 came out in beta this morning, which addresses some issues with the garbage collector - although I doubt that’s what was causing your problem.
