This game is super-unbalanced. Strong players getting more and more stronger super fast, while weaker players have no opportunity to get strong. Only a veeeery slow rate... which increases the already unbalanced situation. And this is only one of the major problems. This is a common illness of games having "buy stuff for kreds". You can make real progress by spending real money. If you don't, then you game a very tiny opportunity to make progress. And then, they add a "PVP"-ish feature, and you have to fight against ppl spending thousands of USD. And for a prize you get stuff to get stronger. But, as a weaker player you are unable to get high ranking, so you'll get some crumb. Super sad.
Recently if I open chests with the detector, a bug happens, and the chest opening animation will go in an infinite loop. Thus, I lost my "trasure"...... :(
Okay, I'm done with this game. It is one thing it stole 2 stars again, but now I did NOT get the extra guildians after completing a stage. I think the little guys killed the boss while I was offline. And I won't pay a kred to continue this. Hopefully I didn't pay any before.
