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.
