Hi Tomo, thanks for playing. I can't believe you found a way to copy build Geysers. Not sure how that was possible since I thought I guarded against it by only allowing buildable furnitures to be copy built. But at the same time, I would have never imagined to try it. Very amusing.
Good eye on catching the jumps in Camera movement. I've changed the camera system a bunch over the past year, it's become a spaghetti. The fixed increment rotation is also a fruit of that. There was a time when the camera was more isometric.
The map size will stay fixed. But it will probably be bigger than the current size, and will be adjustable from the start menu.
Not sure how you produced or found a floating block. Building walls block by block is interesting. Your urge to dig further down is also interesting. Perhaps the familiarity to Minecraft brings these desires to the surface. Or perhaps the voxel system itself lends the game to these possibilities. It certainly sounds fun. I'll see what I can do to make these possible. Thank you for these insightful observations.
