The gameplay in Guild of Heroes is just as you would expect: touch the screen to move your character freely through the (small) settings and tap on enemies to attack them automatically. At the bottom of the screen, you'll see a few different skills that you can choose from, which result in more damaging attacks.
The missions in Guild of Heroes are relatively short, lasting around two or three minutes. Between missions, you can visit the main town in the game. There, you can buy new equipment or sell pieces you no longer want.
Guild of Heroes is a traditional RPG. Although it's not very original, it's still a fun game with excellent visuals in a kind of charming Dungeons and Dragons style.
