A game with a good concept, but it is hardly a completed project, not really ready for playing, lots of improvements needed, esp. the combat AI and the user interface need a lot of work.
It's actually not that unbalanced as so many have complained.
1. Use "don't bully me" in Chapter 1 to grind. You fight only the boss and level up fast. Remember to replace your heroes from the tavern as you level up.
2. Hire Hero from "Friend" TAB. (My Kong friends are GOOD fighters. Hope yours too, LOL)
