Key information

Developed by Gentle Gimmick Games, the bullet hell shooter MAaaaaTH! was showcased at the indie game event OSAKA INDIE GAMES SUMMIT 2026, held on October 3 and 4, 2026, at Congress Square Grand Front Osaka. The title was born from a frustration with mobile game advertisements featuring calculation gates where players constantly make suboptimal choices.

In the game's premise, the Math God misinterpreted humanity's wish to avoid such advertisements, trapping people inside a difficult calculation prison. Players must defeat the Math God to liberate humanity. Stages feature challenging gates with mathematical expressions like X+log10(8) and B×√8 that modify variables affecting the player's stats, such as life and movement speed.

Clearing stages rewards players with Quartz items named after mathematical terms like Epsilon-Delta and Zeta Function, which can be slotted into weapons to rewrite the formulas determining their performance. Enemies and bosses also feature math-themed designs, with boss life meters governed by variable formulas.

MAaaaaTH! has been available in Early Access on Steam since June 4, 2026, priced at 659 yen including tax, alongside a playable demo.
