I don't know if you're still looking for a project, but if you're ever interested in a 3D fangame project let us know!
We're a small team of 2D artists 3D modelers, and animators working together to bring our Fan project, Tails Adventure: Armada, to life!
We have a programming team working in unity, C#, and share everything via GitHub.
We are picking up the pace trying to figure out our mechanics and can always use the extra help!
If you find that worthwhile please let us know!
