Just tried it out, great experience! Intro was well done, the hand mechanics were cool, and the Glados-like character with the hand-reference humor throughout was done just enough to be really funny/enjoyable. Took me a little bit to get used to controls (the bow) as I assume it wasn't made with Vive controllers but still worked fine once I got the hang of it.
The music stopped playing for me about halfway through the second to last level (I took my time). I also got stuck on the last level as it seemed I couldn't pick anything up - I carried my bow in there with me and the other bow/hands were on the ground but I couldn't pick them up; when I shot enemies their dropped hands weren't available for pickup either so I didn't get to complete it.
Thanks for building a Vive version so I could try it!
