If you enjoy Rhythm games and light RPG's then you should buy Sequence on Steam because it is damn good.

It's a light RPG with rhythm game combat that works sort of like DDR or Boom Boom Rocket. It has some real funny dialog and some decent beats to fight your enemies with.

Its normally 5$/4€ and that's a steal but now its half off so you can't say no: http://store.steampowered.com/app/200910

Here is a good informative video of the game by Totalbiscuit if you wanna see how it plays:
