McOsu is a rhythm-game practice client for osu! standard beatmaps. Players follow music-synced patterns of circles and sliders, clicking or moving to hit each note.
Play maps at their set pace or adjust settings such as approach rate, circle size, overall difficulty, HP drain, and playback speed. Scrub to a chosen point in a map, or save and reload positions to revisit sections.
Additional options include experimental gameplay mods, changes to settings and mods during a map, VR and first-person modes, a live pp counter, and offline profiles with local pp rankings. McOsu supports standard beatmaps, not osu!'s other game modes.
Players who enjoy McOsu often value its flexible practice settings, tools for revisiting parts of a map, and options such as VR and first-person play. Some also praise its live stats and responsive feel. Reviews also describe setup and map-loading friction, and note that its appeal is limited for players seeking other osu! modes, replays, or online competition.

McOsu is NOT osu!
A free open-source circle-clicking rhythm game client for osu!(standard) beatmaps, with the main focus on making practicing easier and customizing gameplay.
It is primarily a practice client for getting better at the "official" game by having tools at your disposal that osu!(stable) does not provide for some reason, it's not supposed to be a perfect copy of osu! though it does get close enough where necessary.
If you have never played osu! before, then I do not recommend using this client (except for VR players + FPoSu players of course), because there are no gameplay tutorials to be found here (just google "osu!" and play the official game which is a lot more polished and has online rankings including multiplayer support etc.).
McOsu only supports osu!(standard) beatmaps, while diffs for other gamemodes like mania/taiko/ctb/etc. are simply invisible.
Unlimited Customizability (Options, Console Commands via SHIFT + F1)
Beatmap Overrides (Approach Rate, Circle Size, Overall Difficulty, HP Drain)
Speed/BPM Slider
Scrubbing and Quicksave/load (SHIFT and F6/F7, rebindable, jump to any point in time of a beatmap)
Experimental Mods (Wobble, Jigsaw, First Person, Playfield Flipping, Reverse Sliders, etc.)
Change mods and options while playing (F1 and CTRL + O)
Built-in pp counter (live stats overlay + ranking screen)
VR gamemode
First-Person 3D gamemode (FPoSu)
Steam Workshop support for skins
Infinite offline profiles with pp ranking
Customizable HP Drain + Notelock algorithms
If you have osu!(stable) installed, then McOsu will load your beatmaps directly from the default osu!(stable) installation path, although custom paths are also possible
You can use McOsu without installing osu!(stable), it is not recommended though. A guide on manual beatmap management is available in the Steam Community Guides
Creating an official osu! account for downloading beatmaps is not required. You do not have to use the official osu! website to download beatmaps. Third party beatmap mirrors are available, just google for them
The intention of this game is neither to replace peppy's client, nor to split the community. McOsu was created partially out of frustration, because osu! is lacking many usability features vital to practicing effectively and efficiently. This is currently being rectified in the rewrite of osu! (called osu!lazer), which is an open-source project anyone can contribute to as well.
As a wise man once said, "plz enjoy game".
