so... you have many characters with different classes, in order to level up or get good items you have to do timed quests (12+ hour refresh time) , it will give you money to buy packs
and you can build your own map and publish it
I'm more into smashing enemies, I'm bad at building my own maps lol
but that's what makes this game unique
the other down side is maps made by other ppl are sometimes....bad like unreachable treasure chests and many mobs in one spot, so watch out for its reviews or please review any maps you've played if there's any bugs
