Thanks really appreciate the praise!
Yeh the tracking itself is actually quite good: I disabled the 2d visualization last minute as it was just too many hands on the screen :) Main challenge was in translating the 2d points of fingers into a rigged 3d hand bone positions. But outside of a jam time-constraint should be doable to make this feel way better.
Planning on doing some bugfixes and improvements post jam, as well as add another level.
