It'll be a little while before I can integrate the slopes code, but this version should still work with 3.2. It will just ignore any slopes that you add to your scene.
i tried compiling a project with plat+ on 3.2 and it could not compile regardless of having slopes in the scene or not
I tried to upload a project of mine with the latest version, and it gives me problems too
The base plugin should work, but the camera and gravity plugins won't work in 3.2
just tried it with only the base plugin and the game compile
