Unique approach to locomotion, I liked it! I saw all the warnings in discord, and remembered to play seated. Didn't get sick playing, but I wasn't able to turn at all (index controllers) even after fiddling with the controller bindings in SteamVR. I was able to get a few pieces of candy, but wasn't able to finish the maze.
I had a bit of trouble getting momentum at the beginning, since I kept hitting the ground partway through a swing, but I got a bit better after playing a bit more. It might make players sick, but maybe adding a button to pull the pumpkin towards the grapple point would be something to experiment with?
Overall I'm impressed, I can see you put a lot of work into it. Keep at it!
