Lunacid is a dungeon crawler inspired by games like Shadow Tower and King’s Field.

The game was initially released as Early Access title on March 15, 2022. After over a year in early access and multiple content upgrades it officially graduated from early access on October 31, 2023.

As of November 3, 2023, the game offers a number of basic options that one would expect from a PC title and even supports Ultra-widescreen monitors. However, the game suffers from the fact that some visual elements are updated only 50 times per second, regardless of framerate and monitor's refresh rate.
