## Why It's Good For The Game
its silly for things that arent visually tiled to use the tiled water
sprite
## Changelog
🆑
fix: stuff like carpet and wood tiles dont use the 2x2 tiled sprite
fix: similarly, floors that dont use the tiled sprite now can have
permafrost sprites (as they are not tiled)
