I love this game, I almost gave it a 5 star rating. However, I think it needs major balancing, once you get past tap level 600, your hero is very weak. You rely almost completely on heroes, which basically takes the point away from the game, seeing as how you could just collect offline gold and progress just as much. Also, there needs to be a better use for gems, why would I ever spend gems on reviving a hero that is completely irrelevant? And why would I waste gems on gold when I am just going to prestige anyways? If you made gems more valuable, then not only would you progress faster, people might actually buy gems.
