Quick! Summon a Demon! is a dark humour game where you're trying to summon a demon to escape the cops after you. The problem is that you don't have time to read the grimoire properly, or gather all the ingredients, or actually do the ritual like you should. So winging it it is!
Maybe nothing happens, maybe something does... and maybe it goes horribly wrong! In any case, it's fun to figure out what combination to make to get all the different endings. And the combinations can be pretty silly!
