Just finished playing this. So good! Level 21 is incredibly satisfying. I was surprised to see that it's a Ludum Dare game because of how well designed it all was.
A fix attempting to resolve the Vertex Buffer fatal issue has been posted. See TNLoGI-VertexCompatible.exe in the downloads. Please let me know whether or not this fixes the issue if you originally had it.
Thanks for the message. I have attempted a fix (see known issues in description), but cannot be sure if it works as I can't replicate the crash on my system.
