Rysy

A WIP map viewer for Celeste written in C# using FNA.

If you wish to make maps, just use Lönn instead.

Setup

Clone the repo, get .NET 10, and build.

Run the program, and it'll ask you to select a Celeste install, then a map .bin to load. You can drop both of these files onto Rysy's window.

Features

Super fast load times (even faster than Lönn), thanks to multithreaded lazy loading.
Renders all of 9D (at least the entities that have plugins :p) in ~1.5 seconds on my pc
Colorful debug logs!
Doesn't lock mod zips forever :p
yea, that's about it, just use lönn lol

Why?

Because it's fun, and I also want to make some nice to work with rendering API for potential future projects.
