Cyan Brain is a decadent, sci-fi horror side-scroller developed by NEKOUJI STUDIO. The game blends fast-paced shooting action with dark, "ryona"-focused storytelling, set in a desolate world of deranged machines and religious ruins. Demo 8.1 & Game Evolution
Option 2 (Enthusiast / Dev shoutout):
The "Cyan" effect has been overhauled. In earlier builds, it was purely visual. Now, it’s mechanical. As your exposure to the cyan light increases (by lingering in lit areas without solving puzzles), the game begins to strip away your HUD, invert your controls temporarily, and even replace sound files with corrupted static. The demo 8.1 introduces a "Saturation Meter" hidden in the pause menu. At 100% saturation, the Demo 8.1 forces a unique game over where the player character’s model is replaced by a cyan-lit skeleton. Cyan Brain -Demo 8.1- -NEKOUJI STUDIO-
