IMPORTANT INFO !!** Paul L. @paul612 who left last comment is a scammer. He wanted me to test his .apks but he couldn't even build them properly and they didn't boot up at all! And then he wanted me to develop for him for free. Don't be like @paul612, be honest and I will be honest **** I have done a lot of projects connected with virtual reality, Oculus Rift, Oculus Quest / GO and HTC Vive (I developed unique calibrating system for making free roaming VR Arena). Also I have a some knowledge about design, drawing, 3D modeling, and sound engineering because for some years I have been making games utterly alone. I am not afraid of any kind of challenge. === If you do not speak English we can try to communicate via translators I am sure that we will manage to do it :) 減らす
