A downloadable game for Windows

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.

I think I finished it!

Wow 😲

This is really cool! The world is fun to explore, and I especially like the music. It is kind of confusing to navigate, but that's part of the charm of Yume Nikki-style games
