About This Game

"Act! Autonomy" is a free-input rhythm game. Use your own unique fingering style to defend humanity's artistic privilege.

Rhythm Gameplay

An Unbound Performance Experience

No tracks. No fixed key bindings.

In Act! Autonomy, the notes on the screen are not tied to specific physical keys. You can press ANY key on your keyboard or controller to trigger a hit.

But don't get cocky—it's not just about mashing buttons. To achieve artistic perfection, you will need to strategize your fingering just like a pianist to find the optimal performance path.

• 🟥 Beat: Anchor your origin. Repetitive strikes on the same key to confirm the pulse of life.

• 🟩 Flow: Go with the current. Slide across keys with one hand to untangle the flowing consciousness.

• 🟦 Tech: Interweave. Switch flexibly between hands to stitch together fractured melodies.

Are you a chaotic "Noise Maker," or an elegant "Soul Tuner"? It all depends on your fingertip strategy. (Though, to be fair, making noise is also an important human trait!)

Relaxed & Immersive "Lay-Back" Gaming

Say goodbye to artificial difficulty and "Stamina Checks."

• Scoring System: Precision and combo count are no longer the only standards. Act! values the Artistry of your performance. Weave your own fingerings—immersive play yields higher scores!

• Chart Style: We value emotional expression over raw hand speed. Experience the "flow state" of improvisation within your freeform movements!

• Play Environment: Good posture? Keyboard is king. Exhausted after a long day? Act! might just be the best rhythm game for lying on the couch with a controller!

Share Your Creativity with the World

Be a Creator, not just a Player. Act! features a powerful built-in Custom Chart Editor. You can arrange notes freely, design your own tuning sequences, and share them 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.

Narrative & Systems

Fragmented Storytelling

No long-winded dialogues, just slowly permeating subconsciousness. In Act!, the story is hidden within fragments and items. Piece together the truth behind Act World during the brief rests between songs.

Collection & Progression

As you progress, you will unlock various practical support items. These items help you achieve achievements more easily or unlock fun collectibles—without affecting the fairness of competitive scoring. Aim for that 100% Collection Rate!

Full System Support

We are a mature rhythm game with everything you need. Beyond the Chart Editor, Act! provides all the essentials: A/V offset, latency adjustment, play statistics... It's all here. Play with peace of mind!

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!

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI tools were used to assist in texture generation for some scene elements and UI assets (excluding character art and CGs). However, all initial concept designs and final assets are hand-drawn, manually retouched, or heavily overpainted by the developer to ensure artistic consistency and originality. No raw AI output is used directly in the game.

Mature Content Description

The developers describe the content like this:

This game contains anime-style characters with revealing outfits (e.g., implied partial nudity or suggestive clothing). Some collectible items feature text references to mature humor.

The story explores psychological themes including self-sacrifice and mental struggles. While the narrative includes metaphorical depictions of a character consuming their own life force (interpreted as self-harm ideation), there is no graphic depiction of suicide or extreme violence.
