4 stars: So far seems a good game. Some QOL updates I'd like to see to get a 5 star would be when pressing on a characters ability a pop up would show explaining what that ability does. The same for items as there's been a few occasions where I have had the chance to use an item to clear some debris or another challenge and I haven't known which item is which until you get out of combat. Solid game overall.
3 stars: Good so far. I like the easy upgrade system for leveling characters and items such as weapons and shields. Still suffers from same
3 stars: Game is fun and addicting. Achievement rewards are also fair for free to play and the currency (Purple gems) they give out is generous, along with gold and hero xp. However, I find that in map #5 I have a lot of gold and almost zero hero xp, a real imbalance. Progress has slowed down, now I only play once I collect 100K+ hero xp to level up.
2 stars: The game lacks depth. I played it for about two weeks and spent about $40 to help get a feel for the game. There just isn't anything particularly interesting or compelling about the game however. No complicated builds or team composition to try to chase. No real competition or cooperation to motivate the player. It is just advance until you can't. Wait 5 hours or spend 5 dollars and advance a few more. Repeat.
2 stars: It's okay for the first couple hours but then you reach a plateau or you have to either buy or cease your attempts to try... I've been playing for ...
