About Monsterium

Monsterium is a 2D platformer in which you play as a witch who has accidentally summoned a terrifying creature. You must raise all the platforms and destroy the monster hanging from the ropes, then send it back where it came from. The creature is smarter and craftier than its summoner.

You jump between platforms and cast magic as you try to defeat it. The game features a distinct visual style, atmospheric music and challenging gameplay.
