Oh wow! Thank you for letting us know. We used the generic XR interaction toolkit in Unity, and it should have worked with HTC Vive but we didn't have anyone in our team to test it on that particular headset. Please watch out in a week...after the judging we plan to push an updated build that is less buggy. Hopefully we can figure out HTC Vive compatibility by then :) Thanks for trying!!

it might be because Open VR isn't supported without using the preview packages (for the newest versions of unity) ... valem made a video on how to set it up :) he explains how to set it up around the 2 minute mark... I think I linked the video to start at 1:50... again thank you for your time and effort and look forward to trying out your game :D
