It's a Java game, hardcoded with 32-bit dependencies. So you'll probably be running a 64-bit Java runtime on Linux...which means the game can't find any of the libraries it just assumes are present on your system. Downloading and installing lwjgl 64-bit lets the game start, but then it hangs because it can't find any controllers. Even adding libjinput doesn't help...and I gave up at this point.
