I managed to pull together two more minigames, for a total of 4/8! After two entire days. And there's still no timer, no scoring, no overall lose condition, and no difficulty increase over time. I think the most notable thing I've done today is develop a burning hatred of Euler angles. Trying to do clamp a rotation with the minimum as a positive and the maximum as a negative is bad.

My plan was to finish the mechanics today and use all of tomorrow for art, audio, and general polish, but that might not be totally feasible. If I'm lucky the other minigames will go smoothly, but after the extreme difficulty of "click and drag to rotate the snake around its origin" I'm not betting on it.
