Seamless tiled dirt and grass (almost, it shows back side tile so you don't lose bearings in overworld area).
Seamless tiled raw stone with cobbled look for floors
Brick walls with corresponding edge for flooring so multi-floor tiles smoothly
Seamless smooth parged walls and floor (looks like concrete)
Comes with matching window pieces but they're just decorated walls (for brick and crete)
Seamless tiled wood plank walls/floors (yes!) - still shows plank ends random-spaced
a few other misc additions. it's here if you need it, I actually modded it into your mod on my end because I made it for the base game
Totally free of charge, your project amalgamation is totally awesome.
I will buy you the Blueprint Tycoon game on your wishlist if you'd like also as a donation - let me know.
