The tiles used in the secret level 7 of the obscure Famicom game Gimmick!. The level seems almost serene, it is quite low in difficulty, especially compared to the preceding stage. A very challenging final boss awaits you at the end.
The castle front is just as cutoff in the source game as it is here, but it's sort-of hidden by a screen transition in the source game. Not much to be done about it, really.
