Hiya, I'v been working in game industry for 6 years, I have developed 9 projects on unity and 2 of them took more than 2 years. 4 of them have mobile version and some of them already have swipe, double finger swipe, tap, double tap, press and hold gesture detection logic. So this is relatively easy for me, and it sounds like a intensive fun game which I guess I would enjoy doing it as well.
