The health minigame is pretty hard, but it isn't too bad, seeing as Health only caps at 100%.
However, I would like to see the minigames have difficulties you could select. You could get extra points for an insanely hard difficulty and average growth for normal.
Also, the stamina game is horribly slow compared to all the other stats. It makes all animals with great starting speed horrible later on.
