This is definitely one of the most underrated gems I've ever had the pleasure of playing. I loved Guacamelee! but I remembered when they dropped this one I didn't give it much attention. Then I got it on the 3DS a few days before the closure of the eShop since it was super cheap, and then I couldn't believe when I saw myself not being able to put it down. I loved it so much that I downloaded it on my Vita a day after beating it on the 3DS and platinumed it in a single afternoon. Got it on iOS just the other day and I definitely need to revisit it.
It's a first person dungeon crawler with some heavy metroidvania elements going on, Guacamelee! graphics and touch-based combat, and one of the very best at that. It's an extremely well crafted and addictive game, and it's bigger sin is how obscenely short it is.
