Our take on Calturin

Its defining structure is a portal-based boss rush: progression moves through the Gauntlet of Portals toward 8 boss encounters, with alternate red and black routes adding harder challenges.

What is Calturin?

Calturin is a bullet-hell boss-rush game about a resurrected character controlled by a necromancer.

Freedom is offered in exchange for completing tasks across the Gauntlet of Portals, which leads to unfamiliar lands and dangerous encounters. The game includes 8 distinct boss battles, 2 difficult routes, and a confrontation with an army. Characters deliver the story through full voice performances. As the character grows stronger, players choose how to develop their skills. Red and black portals provide additional difficulty for players seeking a harder challenge. The structure supports both a standard playthrough and speedrunning.
