3D Fan made Sonic Game

[iyenal]

I started developing a fan made Sonic game a few days ago and any C+C would be great, here'a a link to a YT video I made on it if anyone's interested: https://www.youtube.com/watch?v=C7UIZ3yxNs4  

I'm developing a Sonic Colors game forandroid with Unity3D.
What engine you use ?

If you watch the video I gave a link to, you'll see I'm using UE4.

If you want some stuff for you game, I think it's a very good pack : http://info.sonicretro.org/SonicGDK
I cant use SonicGDK because it's for UE and I have a bad experience witn Unreal Engine.
I think Unity is more simpler.

I've seen your video but I can't recognize UE4. Sorry .
