GAMER LOUNGE 20XX (NO CASUALS!!)

[Jermungandr]

While I agree with your recommendation, I really would not describe the game as a "Metroidvania" title in the slightest. The level designs are very straightforward and open, just with secret areas smattered throughout them that you'll have to discover if you want to 100% the game. Rather than Metroid or Castlevania, if I had to compare it to any game series I'd probably go with something more like Mega Man X, or maybe a Donkey Kong Country game without the bonus-games.
