I enjoy it because it is challengin, the mayor chests are rare though I've only received one, the other game they released recently which I enjoy is the Poseidon event where you go fishing, both don't need to spend money but get decent rewards
I like the rewards, as well. Quite a relaxing event. I don't know how you could even go 12 hours in the Maya event. I did it once and just left it as it was. No backtracking to get better scores. Didn't even want to do it until I saw some videos on it.
