Something I've been putting together in the miniscule amounts of spare time I can find (having a baby to take care of) for Arca. Tom told me I couldn't show off the graphics but he didn't say anything about the level itself, so I changed to the Classic tileset. It's a little less vibrant like this, but both tilesets feel Classic enough that the level is nice in both.
Remember though, it is a Classic level and isn't supposed to be swamped in new-fangled detail styles or houses
Edit: Yes, I have noticed the tile error in the bottom right. It's something of a pain, as the error with the Arca tileset is only a single pixel.
