I have not approved any use of the proof of concept as it needs a fair bit of updating which I'm unable to spare time for currently.
Really appreciate you being interested in seeing it become a proper game asset somehow though!
I probably get the most use out of living wood and leaf blocks across all biomes. vine-covered buildings, kelp forests, cherry trees. All possible with a little paint.
Cobalt bricks are fantastic for anything remotely water-themed or aquatic. Even just as bathroom tile.
Particularly excellent work on the snow cottage. I would say for the sake of 'realistic depth' I'm surprised the trees are blooming in winter though ;) must be magic.
If you don't mind, I have to steal those diamond windows. They are great!
