CTB-Editor
An editor for osu ctb made in Unity (WIP)
If you want to tinker with the code you need Unity 2018.1.4f1. Later versions are not guaranteed to work.
Contributing
The editor is at a very early stage so it's open for suggestions and it's relatively easy to join the dev team. We have a discord where you can ask anything from request to pull requests. https://discord.gg/TqaTtGZ
