Nightmare Castle

Nightmare Castle is an extended technical demonstration and a surreal adventure game from 2013-2014, built as a platform to test reduction and refinement of RPG Maker's VFX to PC-88 or early PC-98 standards. As such, the game uses 3-bit graphics at a resolution of 640x400.

Unlike Amihailu in Dreamland, the gameplay is a direct descendant of Yume Nikki.
