Ad scam. Stopped at level 3 because there were no options to increase the bag size without watching double ads. I have no doubt this comes on top of forced ads. This genre is saturated with better games, don't waste the drive space. The five star review is a scam, a game listing as free with ads is not a 5 star game if you're required to buy a no-ads option to make it playable. Devs deserve money, but no one has money except rich people....

Fun game. ads are optional and not forcing (so far). I can get really far without ads... I like the library feature and can know before each stage which kinds of monster will appear. However I cant change weapons setup before match, must go out and rearrange.. Dragons should change appearance in map based on their levels. The icons on right side are stretched if ratio not matched.. Cant save progress...
