I Love clicker games like this. I loved ClickerHeroes and ClickonTitans; now I also Love Tap Heroes.
This game isn't hard at all and the click to heal self was a great input into the game play. With all the other clicker games you could afk and know you'll kill the bosses without having to do a thing.
Maybe It's just me but I don't understand why people are complaining about making GoldxGems.
I'm @ 980 and I've been gaining a crap ton of gold and gems. I've noticed that Gem boxes keep on appearing on the same stage as long as you don't level your heroes that much higher then the level requirement.
(Stuff in need of improvement)
1. Need more items in the [Extra Store](
2. Familiar and Banker should have a level increase higher then Lvl.3 so people can pick which one they want most.
3. Maybe It's time to add another Hero? Like a Wizard (Burn/Freeze damage). The Wizard would be Floating Behind where the Familiar is Floating (So above the mage and rouge).
[Wizard Tips]
1. Make the Wizard a (WANTED) Hero so make Her/Him 10-20 Gems.
2. The Wizard Would Cost 2x the Amount of Gold then the other Heroes when it comes to Upgrading Her/Him.
Hope the game keeps on improving :D
