Picked up a 2DS and downloaded Aeternoblade and Gargoyle's Quest (amazing GB game, GET IT

).
Aeternoblade is a 2.5d metroidvania game with modern hack n slash attacks and leveling system. It obviously takes inspiration from CV and the Valid games (yipee!! Some love for Valis!).
So far, at stage 2, graphics are mixed, some good, some badly muddy textures, pretty decent animation. It's a good looking game till things zoom in a bit.
Gameplay is quite good. While the combat isn't out of this world exciting, it has a really good duel relics system (akin to COTM), and it has good simple puzzles. Plus, the controls and movement are VERY satisfying (a step or two behind Alucard imo). One thing I like about it is that rather than the satisfaction relying solely on the combat, its the movement and methods you take in conjunction with the combat that makes it feel a bit more old school.
I'll beat the game before I recommend it, but hey, it is on sale right now, and its a good game so far. Also for PS4 and Vita.
