Games like Infinity Blade are just too much hard work. You have to swipe up and down, tap and double-tap, and remember all sorts of gestures.
Part Time Hero:Monster Mayham, by Appzil, is dubbed the "easiest hero game in the world". All you need to do is let your hero fight by himself while you watch and touch the screen to swing his sword. Fight 10 monster waves in each chapter as you progress.
Still, your hero can't quite do it all himself. He needs someone — you — to help spend the hard-earned loot on weapon and equipment upgrades and even sidekicks. These are no ordinary sidekicks, they are salaried, so you will need to budget carefully. Sidekicks or equipment, sometimes you have to decide one or the other.
Download Part Time Hero:Monster Mayham from the Google Play Store. The game is free, though supplemented by in-app purchases which can help you advance quicker. These are not necessary in order to play the game, as you gain coins through fights, but if you enjoy the game I always recommend supporting the developer.
