That was a blast. I also completed it in one try, with 12 seconds left! I just was wishing there was at least one more level. There's a lot of potential here.
I've always loved puzzle games where you have to switch between two or more asymmetric characters (Lost Vikings, Gobliiins). VR gives it an added coolness because you can wave to yourself. Could be explored further by giving each potato different abilities.
UI confusion: I was quite confused about the orange box in the first room. I spent a lot of time trying to pick it up to give it to the other guy, but it turns out it was nothing. Also it wasn't clear when I pushed the door button that it was permanently pushed (so I just had to push both buttons) - I thought I would need to find a way to have both guys push it at the same time. A bit of user experience polish would help here.
But the thing that was super cool was shrinking yourself down to go inside the little house. Nice work.
