The game installs and runs fine, however there are some issues: the mouse which has limited movement and some very rare pieces of grass don't render correctly and have wacky colors.
The mouse problem can be solved by adding a registry key in: HKCU/Software/Wine/AppDefaults/EiB.exe/DirectInput/ named "MouseWarpOverride" and set it to "force". Probably EiB.exe won't exist so you'll have to create it.
