Daav Valentaten of Gamesta did a nice Preview of Axiom Verge:
The man is currently creating oldschool gold with Axiom Verge; a Metroidvania game straight out of the 16bit era. He’s singlehandedly creating this title that just screams nostalgia; complete with gritty, obscure graphics and tons of exploration.
I also like this one:
there’s also a slight connotation with bizarre title Mystic Defender on Mega Drive
Anyone remember that game? It was one of the earliest releases, possibly a launch title. I always like the destruction effect for the creatures, a kind of glowing orb of incineration that goes left to right with the direction of your attack. Some of the explosions in Orn were based off of that effect.
