Steam Store description

McOsu is developed separately from and has no direct affiliation with osu! or ppy Pty Ltd. 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. Features: 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 Customizab…
