Yep, that's the lwjgl OpenGL error. I need to figure out how I can handle it, because there appears to be a resolution, but I'm not sure exactly what causes the issue and how to detect it ahead of time. I'm going to try a workaround and see if it works in the general case.
Here's the description of the error - it's a bug in lwjgl, as far as I can tell: https://github.com/libgdx/libgdx/issues/997
Alright, the fix seems to have isolated the issue then - we're trying to force it to give the all clear, but if your video card doesn't support OpenGL 2.0 the game just can't run. D:
The next version we're putting out will actually pop up the error on crash without you having to run it from the command line like that, so it'll be more obvious what the issue is. Thanks again for giving it a try, and glad to hear that it works on your PC - I expect a lot of the people having issues are running the game on integrated graphics cards on their laptops.
