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.

Game is fun but 1000 draw party event is not working. It says I have earned 10 keys every day but they do not show up in shop or inventory. It's my 6th day and I've already missed 60 keys. Also there had been other cases that I've claimed keys from daily activity or daily login events and they did not appear. Will raise stars if fixed and missing keys are given.
