I pressed space while holding the left arrow key to try and jump (before I discovered that arrow up jumps), and the game just crashed. So I reopened it, tried the same thing to see if it was a fluke, it didn’t crash. So I just kept going left. While I fell off the world at the side I tried it again, this time the Unity crash handler window appeared and immediately locked up my computer. I had to hold the power button to force it to shut down. I don’t know if that is a bug caused by running the game through WINE. I also tried running it in the only Windows install I have ready to go, a Windows 7 VM, but it just errored out and told me it couldn’t run the file.
