Failure of CreateEnvironmentBlock seems to be an issue with multiple games. It doesn't seem to be getting to the point of actually running the game, so I don't think there's anything I can do it about it. Might be related to: https://github.com/itchio/itch/issues/833
If you suspect that it's actually an issue with the game, you could try running its .jar file directly via the command line and letting me know what it prints out.
