Indeed. This one and Psych as well. I remember, when I was reworking my single player levels (which STILL haven't been released, but that's not the point), Carrotus and Psych gave me the most work simply because I had to fix so many tilebugs I made when I just took those chunks of tiles as they were in the tileset and pasted them in highly repetitive patterns. Except they didn't fit all that well, especially on the edges. And at least in case of Carrotus it was a matter of replacing tiles, with Psych because of how the grass and slope tiles are designed I sometimes had to redesign portions of the level to make it look good.

At least Inferno clearly shows it's gonna give you one hell of a work...
