Thank you so much for this feedback! It makes me really happy to hear that you are having fun with it. The climbing is also one of my favorite mechanics. Climbing in VR just always feels so nice.
I hope that you do not run into performance problems when placing too many objects.
At some point I would love to visit your world. I plan to make the register feature part of the client in one of the next updates (at the moment I need to create accounts for uploading worlds manually)
Thanks again! cu
