Everything looks good so far. No annoying push ads but my suggestion is to add a trash bucket where we can sell unwanted merges like today after merging the attack type hero i got 3 Frost hero of level 3, 2, 1 which is totally useless, no one to attack. There is no option to change, swap, or sell them. As a result, lost in the beginning of the game.

not a bad game but could be way better. The monsters come out too slow n the game drags slightly. Getting coins is slow, to even get another character on the board. also, there's a bug in coop. some of the characters don't merge. u can't do nothing with them even tho they're there. yeah overall, pretty slow burner this one.
