In my new project I am going to  combine Hyper  Casual Mobile game with an elements of crossfit and fitness .   Total hardware's weight will be  about 1-2 kg (  with gadget included).

I want to use only onboard sensors without  any additional Bluetooth or WiFi  remote control. 

Target group for such kind of entertainment incudes  Harry Potter fans who like fitness ( crossfit) as well as mobile gaming in its modern minimalistic  form called " Hyper Casual" gaming.
