About

The Gameboy Clicker game that nobody ever even asked for! Created during GGJ16 In ~24 hours with mild panic everywhere around the theme of "ritual" heck, there's nothing more ritualistic than a clicker game, let's Gameboy it up. This was the sadly somewhat lacklustre result, but still, it IS a gameboy ROM I made so, here it is in all its glory. Kiss the waifus.
