Unfortunately the only option is to send me the log files. I just uploaded a new build that should eliminate any input system-related issues, but if that doesn't work, the new version should also compile log files that might help get to the root of the issue.
If you'd like to help me fix this bug, the log files will be in the following directory:
(Your Drive):\Users\(Your Name)\AppData\LocalLow\Mangosauce\Turk's Crawling Dungeon\
The files you'd want to send me are TCDLog.txt, Player.log, and Player-prev.log. You can send those to mangosaucedev@gmail.com and I'll work my butt off to get to the bottom of this strange issue. Otherwise I hope I can fix things along the course of development. My goal is to make this game as accessible as I can make it and freezes/crashes like this are unacceptable!
