That is very strange. I can work on trying to optimize the memory a bit more in case it's a memory related issue, but I haven't seen those issues come up in testing. Sorry that it's doing that to you...
For memory related crashes, it's a bit weird. Its not related to how much memory your computer has, but rather how much memory your computer arbitrarily gives to the game. I don't know why, but some computers assign less memory to the game than most others, even if they have a lot of memory available, and then the program is closed if the memory usage exceeds what is allowed.
The game does not generate log files when run as a standalone. Though, if you find a crash occurring in the same spot consistently, then it wouldn't be a memory issue and I can look into why that crash is happening if you let me know where it is. I did upload a few optimizations since your last reply to further reduce the memory load of the game so hopefully the newest version will be more stable for you.
