The cave painting and diamond minigames took me some time figuring out, but other games were pretty straight-forward after few tries. In endurance mode I found, that the Diamond Heist is pretty slow in comparison to other mini-games. Also I tried starting at speed 3.0 once and it turned out the Beach Walking mini-game is unplayable at that speed; feet move so fast, you can't even turn. Other than that the game was really enjoyable.
