I just have to say, whoever painted the artwork did a remarkable job of copying Ayami Kojima's style. I highly recommend checking the artist's other pieces.
This game may look like a metroidvania but it's actually a side-scroller. For an actual metroidvania game, you might want to check out Touhou Luna Nights.
think of a good little game best metroidvania this year soundtrack excellent gameplay good, it reminded me a lot of old castlevania ehehe I made a gameplay of the beginning of the game go check it out.
