Hey,
I've been working on a 3D tennis game where you use the crank to control the racquet in an intuitive way.
There is still a bunch of work to do including adding the opponent and scoring and polishing it overall. I'm also not sure how to make it more enjoyable long term and was thinking of either adding some kind of progression to it or sizing down the game to be 2D and more arcade-y instead similar to Off the Wall.
It was challenging in a fun way getting it to run 30 fps on the device, and involved relearning linear algebra and differential equations. The graphics are rotoscoped and I'm really happy with how they turned out given I had no pixel art experience beforehand.
Thanks, I've been reading the other posts in this forum and they have all been inspiring!
