Some might suggest that the DS already has a massive amount of RPG's and they would be correct in syaing that, however none of them have combined RPG elements with puzzle solving skills with ease until now.
Clash of Heroes is a bridge that offers puzzle solvers a look into the depths of playing an RPG-esque game whether you tend to play Tetris or Professor Layton games, Clash of Heroes will capture your attention. It has a vibrant colour scheme and gameplay is simple to begin with but the tutorial will be at hand to guide you through the first steps.
You can easily accumulate over 30 hours in to this game and for something to pick up and play on the go it will always satisfy you.
Overall this is one of those games that has gone unnoticed by the masses but I would urge anyone who enjoys RPG games and Puzzle games to give this game a chance as it wont let you down and can become very addictive!
