Kudos for trying to make something unique and experimenting with new approaches in VR! I enjoyed watching your progress on the Discord, and was really excited to finally play it.
I'm sad to admit that I didn't have enough fortitude to play more than about a minute of the game before motion sickness set in and I had to take off the headset. I think it's the acceleration curve of the motion perhaps? I wonder if there could be an alternate way to control the ball using actual body movement so that the brain works out the motion better. Perhaps by tilting the head, or by rolling the hands in a bicycle motion to control the roll of the pumpkin?
Anyway, congrats for finishing your first jam. I'm looking forward to seeing what else you come up with!
