Thanks for the feedback! The handtracking controls are just what seemed the most intuitive/fun to me at the time, although not necessarily reliable as I discovered too late. I haven't seen other games that use handtracking similarly. This game could have actually been done with controllers so that they track more reliably (e.g. the mouth opening/closing could have been done with the front trigger, and the head just follows the controller), but my goal for the jam was to play around with Unity's XR Hands package, and this was a simple little way to explore it. The funny thing is that I didn't start making the levels until the final 3 hours and was afraid that they would be too easy. :)
