Simply put, Relicta is in a class of its own. Its design is often head and shoulders above many of its contemporaries, the writing is of the highest quality, and the game looks far better than it honestly needs to. Absolutely anyone who considers themselves a fan of the genre owes it to themselves to play this game. It'll take you to the moon.
Cyber Shadow is a truly wonderful game. It's brutal, uncompromising, and insanely enjoyable to a degree that I don't often see. Between its lovingly crafted visuals, pitch-perfect gameplay, and maddeningly difficult, yet expertly designed levels, it's a must-play for anyone who enjoys side-scrolling action games.
Blasphemous might be derivative, but it's one of the best, if not the best Metroid-like I've played this year. Not only is it downright gorgeous, but the gameplay is uniformly excellent and hunting for its many secrets make it a puzzle well worth exploring.
