I've been learning & using the Unity Game Engine on and off for about 2 years and I love it.
I've been part of 3 game jams so far, Manifest Space was product of one called "Indie Galactic SpaceJam" here in Orlando FL. That one is also available on android (see my website for link).
Mr.Smiling VR is a small concept made for the 2015 LeapMotion3D Jam , it was more of a learning experience for me so I could figure out how to detect gestures and work with their SDK
Lately I'm entirely focused in VR and have made several prototypes. I am working on a standing experience that will hopefully support Oculus, Vive, & PS4 headsets.
Feel free to contact me with feedback good or bad, its always appreciated.
