We have engine issues, it is a known Unity bug and on build it crashes the game shortly aftter play.
Please be patient, at this time we do have the game updated and are working with the Unity community to get this resolved.
(These happen on build version):
unity exception thrown at 0x00007FF8E3A278FE (mono.dll)
unity Allocation of 78 bytes at 00000000064B4240
EDIT: We have managed to get a build going that doesn't crash howeer we are still getting 37 red errors, but we are fairly certain we can resolve those in the next day or 2.
Issue was a 'corrupt' shader that didn't like Unity 2017.2, which is fixed, now we have 1 more isseu that is causing all those other errors but it is the same script having issues with our objectpool.
EDIT Dos:
We have only 1 more issue to resolve and then Tutorial, start, lvl1 and lvl2 will be totally working and then we just need to test lvl3 and the maze, for some reason 1 interaction isn't working so right now you can't get the diamonds (in the build not released yet so we will fix it first) but I wanted to keep everyone updated.
RIFT players, we will need a few extra days, the player actually starts below ground and we need to figure out why but other than that it should work the same as the Vive.
