marchc1/CloneDash — reverse-engineered prompt

Build me a playable early beta clone of Muse Dash in C#. I want the core parkour rhythm gameplay to actually work, with hitting notes in time, jumping and attacking enemies, health, scoring, combos, pause, song select, and a simple results screen. It should feel like a real vertical slice, not a finished game, but complete enough that someone can boot it up and play songs.

It needs to use data from a real Steam install of Muse Dash, so add a clean first run flow that finds the game, checks that it is installed properly, and loads the base game levels. Please also support custom albums in the usual .mdm format, with a way to load them from local files and from mdmc.moe in the main menu. Keep Windows as the main target, but try to keep it working on Linux and Mac too. If there is time, leave room for accessibility, training, and customization features since that is part of the point of this project. Look up current docs online if you need to.
