(issue fixed but the connection lost still happens a lot)fun game but after playing for a while not it won't log in anymore. it starts and gets to 60% then I get a connection lost message and nothing. I have tried to re install and nothing helped. after 2 days it was fixed they gave us some gems and keys and other stuff. I still get random disconnects that will make you lose money or items if it happens at the wrong time.

This was a 8.5 or of 10, 5 stars... until the 10 stages. I've been stuck 10-40 for way too long. the only way i see to get past this is to buy more packs or elites. I've already spent so much on the game and yet it demands more. i don't know if its a balancing issue or what but there is a painful wall you hit without buying every pack they sell. game is an 6 out of 10 only because you have to spend so much money to get passed this point.

Not a bad base but many problems. Monetization is EVERYWHERE. There isn't a single menu without some different ask for money. Idle is very misleading, you can earn very very stingy amounts of resources while afk but other than that, game is completely hands on. All progress is hands on. Finally, there are way too many menus with their own needs that has you constantly going back and forth just to tap the screen again and again. Tedium pretending it's game play.
