--- Comment #1 from Ori Avtalion ori@avtalion.name --- Austin, the "download" tag may be slightly misleading. This is a web-only Unity3D application that requires the Unity3D plugin. Since the plugin doesn't work under wine by itself, you also need to use the Pipelight wrapper and several wine patches:

I will try finding a simpler test-case, but for now the printed warning may be good enough to test against.
