So I discovered this thing while looking for Unity-based 2D Sonic engines (after trying to roll my own and failing), and this is almost what I was looking for. The main problem that makes it completely unusable for what I want to do with Sonic physics, however, is that it doesn't work with Unity's 2D collisions, which is a big problem if you want to use tilemaps, which basically require the use of composite colliders, which don't have a 3D equivalent.

Been trying to fix this myself by setting up a 2D mode on the motor that constructs a 2D rigidbody and a 2D collider instead of the regular one and with dedicated functions for handling collisions with 2D physics, but the resulting physics just send Sonic flying into the stratosphere for no discernible reason.

But despite my issue, this engine is pretty goddamn sweet, I just wish it could work with 2D 2D. Also, some of the assets in the engine need updating for newer versions of Unity.

Translating the engine to Unity 2D physics will not be very straight forward. Despite it might look like, 2D and 3D Unity's physics API behaves in a different way and my experience with the 2D one was not very good. In fact, I won't even recommend using it if you ask me. I committed a big mistake using Blender assets directly in Unity, maybe in the near future I release an update for it. Thanks for the feedback!

Yikes, no wonder. Might actually go with your 2D physics in Godot instead in that case.

You'll have problems with it as well, I didn't really made that Godot project to be used in any fan game and it have a lot of bugs.

Well. Damn.

Granted, I'm not actually planning a fangame, but goddamn is it frustrating to find out that there are no fully functional 2D Sonic physics implementations in any "modern" engine, and I think you're the only one who has made a properly working 2.5D implementation, outside of maybe Dash Engine in UE4, but I cannot for the life of me get that to work because of its weird build system not working.

Then again, I think it might be best to stick to 2.5D with Freedom Engine (or Dash Engine in UE4 if I can ever get it to work) for prototyping what I'm planning and move over to a proper 2D engine later, for a bunch of reasons.
