I have cleared Inverted First Kiln, wonderful level and a really clever way to reuse your already great level design in a fun new way :D
So awesome!
Wait how do you get inverted first kiln? I beat the first kiln but didnt see anything about an inverted one...
With the new 1.14 update, when you beat First Kiln you unlock Inverted Nightmare, once you beat Inverted Nightmare then you unlock Inverted First Kiln
