I developed games for fun, one of them it's in Google Play with 9500 downloads.
I enjoy developing games, so I wont have any problem making your game.
I have a lot of experience with java, android, and unity game programming with over 3 years of experience, I have some game projects made from scratch, if you wants screenshots or something, just tell me.
I have experience too with augmented reality, and I have done some projects with it.
Do you only need the rocking chair to appear on the camera? Or you need too the feature of changing between different types of rocking chairs, and to hook up to a QR target in the ground?
Good day!
