My first time playing -- thanks for the opportunity!
Didn't try spectator mode, as I am only one person.
Overall: Very cool game, but gave me some motion sickness.
The game itself is sweet. Environment is awesome. I love how you use roomscale to avoid the entire locomotion & chaperone issue. This creates a huge sense of immersion. In one of those really thin (1-block wide) corridors with the spike pit beneath, I felt like I was really there! Also, one time I tried to adjust the brim of my hat. You've nailed the immersion / atmosphere IMO.
At first I didn't know what to do with those flying scarab beetles and so it took me 2 tries to kill them. I figured it out, though.
I get motion-sick pretty easy in VR (I usually use teleport locomotion) and I did have to stop playing after an hour or so. [how long I lasted: I had opened the first dual-lock door to get inside the large temple, and then got to that large room with the second dual-look door, with puzzle rooms off to either side, where you complete the puzzle and come back out over the top. I had done one of those side rooms-- the puzzle where that chess-piece style guy is chasing you around on blocks -- which was pretty fun, btw--and then got back to the main room, and had to quit due to motion sickness.].
Anyway, motion while turning or looking to the sides is what usually does me in with VR games. So, lots of cases here where where you'd be on a moving platform, and then turning to look at the next moving or stationary platform as you came to a stop and jumped off. I think that's what really messed me up. I tried only looking forward while on moving platforms, until each platform had come to a complete stop, and that helped a little, but there's often not that much time to wait. But, yeah. All the turning with motion really shakes me up. I did try both smooth and linear platform motion, I think I preferred smooth and would probably prefer smoother.
I'm not sure what my advice is for fixing the motion sickness issue--it will be interesting to hear if other people have the same issue. I've seen other games obscure part of the FOV while in motion, maybe that would help. Making more platforms where you walk directly off the front of the platform, rather than the side, would likely help,
I may go back and try to finish the game later, but I don't think I'll be able to get farther than that--my head is spinning and need to go lay down for the rest of the evening!
Thanks for the fun build! Overall, I enjoyed myself despite the motion sickness.
