First few days it was smooth but after that I was starting to run out of material to use. Heroes requirements for battle is way too much just to keep going in one spot. The hero level can be limited by the castle if it's not high level enough. Worst part is that the game DRAINS my battery very quickly for absolutely no reason and even overheats. In conclusion: boring, repetitive and unfair. Literally no guide to any of the systems.

Pay to win, but can still be enjoyable. There are events that you cannot complete without spending, most others are very difficult to win without spending even if you play 16 hours a day. Most items (e.g. Relics) that allow you to compete are only available through purchases. I have played with friends for six months. It is not a free to play friendly game. It is the people playing that make it enjoyable. The only competitive players in our guild spend over $400/month.

Ads make it look like it's a rougelite, it's not. The preview makes it look like a cozy game, it's not. It's pretty much a pay to win for an auto battle game and requires upgrading facilities to powerup. There is enough to do to keep your attention for a couple days, which is where I'm cutting out, but it's not really fun or dark and gritty as the ads make it look. Why do game devs think that's what we want? Why waste time making fake gameplay for an ad just to bait and switch?
