I created this game using the RGM (Raycasting Game Creator) engine. I also painted the textures in Paint and Paint.net.

the plot of the game - you play as a middle-aged man who stumbled upon a basement about which there were legends about a monster who, according to legend, was an ordinary 12-year-old teenager who went missing (March 12, 1993) and you became interested in wandering there (in vain)
