About
This project started without a grand vision, it was born from a veteran player’s need to break the monotony of 4-key play. It was built to provide a dedicated environment for 6-key adaptation, focusing on high-response performance where the music lives only through your touch. No input, no sound. Only precision completes the performance.
Made by rhythm nerds for rhythm nerds. There is no big-studio fluff here. Everyone involved, from the developer to the testers, is a dedicated player who lives for keyboard rhythm games. Experience the result of our shared passion today.
Every single track was composed by human hands, with zero AI assistance. Experience the depth and soul that AI simply cannot replicate. Feel the genuine human touch in every note. Our ultimate goal is to expand the built-in library to 100 tracks, delivering a massive collection of pure, human-made rhythm.
We never stop testing and refining the experience. Every chart is built on a 6-key foundation, with the core tactile experience hand-polished to ensure a satisfying flow. To help you track your growth, our advanced Skill Test Algorithm analyzes your performance across various pattern types to instantly calculate and track your rating.
If you encounter a pattern that feels impossible, know that it is not a mistake, it’s a deliberate wall built for the top players.
Don't let your journey end with our official tracklist. With the built-in Auto MIDI Converter, you can import your own authorized MIDI files and instantly generate playable charts. Please note that this auto-conversion feature operates based on simple, randomized node-dispersion rules rather than advanced ergonomic chart-optimization algorithms. However, the provided 6-Key Editor allows you to craft and enjoy a customized charting experience that perfectly fits your style. Play your favorite songs or your own compositions, and test your limits with endless custom content.
Notice: Players are strictly required to use only legally owned or authorized MIDI files. We do not condone or assume responsibility for the unauthorized use of copyrighted material.
No constant internet connection required. Play anytime, anywhere, completely uninterrupted. Share the challenge with your family and see who can truly conquer the charts.
"Great music should be defined by its core rhythm and melody, not by flashy production." This is why we stripped away everything but the raw sound of the piano. Our tracks are built specifically to highlight the essence of timing and tactile feedback. Experience the power of pure rhythm, focused entirely on the connection between your fingers and the music.

Reviews
드디어 출시했군요. 저는 이 게임을 베타 버전으로 먼저 플레이를 했습니다. 이미 데모 버전에 리뷰를 남겼으니 자세한 건 넘어가고, 재밌게 즐겼습니다. 앞으로도 신곡이 업데이트될 거라고 하니 기대됩니다.
I had a few issues with the game that made it unenjoyable for me, and the devs added changes to fix it really quickly. Now, it's much more pleasant to play. What I like the most are the lovely songs, and next to it sounding like piano, there's also the fun option to have it sound like chimes, music box, etc. I always love rhythm games that make it sound like you're truly only playing the actual music you hear. They'e pretty rare. The game shows you a graph as to what technical patterns a song has the most, which is good if you want to practice certain ones; you can choose a song accordingly. I still hope they'll consider adding chart generation from midi files. So far, all the charting in the game actually looks like it was done this way tbh. The option to use midi files would elevate this game so much and would replace another game I still use for this purpose that I've almost 200 hours in by now.
