The game keeps crashing midway through the first level (at least a half dozen times so far) due to a "Fatal error. System.AccessViolationException: Attempted to read or write protected memory". I took a screenshot that I'll include here as it has a lot of text afterwards:
Now I am running this on Windows 7 so it may just be a simple "don't run on that, sorry" situation, but I figure no harm in asking if anyone knows a fix for this.
FWIW the first half of the first level seemed pretty neat! :)
