Innovative Rhythm Play

An Unrestricted Performance ExperienceSay goodbye to the constraints of “lanes” and “fixed keys.”In Act!, the notes on screen are not tied to any specific physical buttons. You can trigger judgments by pressing any key on your keyboard or controller.—Of course, it’s not that simple: to reach artistic mastery, you’ll need to explore optimal performance strategies, much like a pianist planning their fingering.🟥 Beats:Anchor yourself and tap repeatedly on the same key.🟩 Flows:Glide smoothly to adjacent keys in a continuous motion.🟦 Techs:Leap between distant keys in an alternating, rhythmic interplay.Precise timing helps you score higher, while elegant fingering accelerates your tuning progress in the world of ACT.A More Relaxed “Immersive Lean-Back Play” StyleNo more intentionally punishing “skill checks” just for the sake of difficulty.Multi-Dimensional Scoring:Judgment accuracy and combos are no longer the only metrics. The world of ACT relies on your artistic performance to overcome challenges. Weave your own fingering patterns freely—the more immersed you are, the higher your evaluation will be!Emphasis on Musical Expression:Rather than testing raw speed, Act! charts focus on conveying the emotion and nuance of the music. Within the freedom of your fingering, experience a state of flow akin to “improvisation.”Controller-Friendly Lean-Back Play:Act! might just be the most controller-friendly rhythm game out there. After a long, tiring day when you just want to lie back and relax, this game will be your go-to choice.Share Your Creativity with the WorldBe more than a player—become a creator.Act! comes with a powerful custom chart editor built right in, with deep support for chart creation using a controller.Step away from the monotony of daily tasks, unwind with music, and unleash your creativity—then share your creations with Tuners worldwide.

Worldview

"Break the mold, awaken the self. Tune the cells, reshape the soul."This is Act World. Here, humans and AI once coexisted in prosperity. But a silent crisis has arrived—a psychological plague known as "AI Somatization." New humans, eroded by AI logic, worship machine precision and efficiency, threatening to wipe out the warmth of old humanity.You drift into the "inner side" of this world and meet a girl named "Little A" (Eiria). She asks you to cure this plague. Your task is surprisingly simple: use your fingertips to tune the cells of the human subconscious and reinject the precious resource known as "Spirituality" back into the world's Archetype.

A Word from the Developer

Thanks for reading this far! I'm paperlens, a game industry "wage-slave" who used to be a Charter, Vocaloid Producer, and Clipper.I still remember the passion O2Jam gave me when I was only as tall as a table. Rhythm games have been with me for 20 years, and I've wanted to make my own for about 10. In October 2025, I finally made up my mind—even without capital backing, I will realize this innovative rhythm game that fits my aesthetics.I handled the design, programming, music, and art all by myself. It might not have the luxury quality of a AAA commercial title, but it is filled with my love for rhythm games. It would be my greatest joy to walk this path accompanied by fellow rhythm game fans! I hope to bring you a brand new experience and show more people the charm of this genre!
