This game is great for the first few months. I really enjoyed all the tasks that they gave you, but then, when I completed EVERYTHING, including some packs that on certain days they gave for free, I grew bored.. There was no way to get mana, except for the tedious quests I didnt want to do, DAILY challenges, and by buying mana. Or, well, also achievements, but I got all of those.
I wasnt sure what to do then, so I made videos, did experiments, and created art, but I got so bored of everything, I quit.
This is a GREAT game, but when finished, Id warn you that getting things you want might not be as easy as it seems.. Onto the overall of this app: Great app, fun, detailed, fair (kind of), optional (as in: things to do), artistic persons dream, and I think that the quests are fun :) just keep in mind that mana is something that isnt so easy to get when youve achieved almost everything.
