Im just started but it seem good so far. A little confusing at first, but you get the hang of it. Alsk looks like there isa lot todo

Pretty fun and simple, only gripe is I personally dislike when the tutorial makes you click here and there for the first 15 minutes before you can discover anything on ur own. Past that it's cute

Really enjoying it so far. The tutorial is quite long, but you can skip parts of it. There are a fair few gift codes to use which give nice rewards too. My main criticism is how much hero fodder is needed to star up - it takes a long time to get the Hero materials needed, which is a bit off-putting. Nice rewards as you progress though, and events are very generous, even for f2p players. Still playing happily weeks later.
