From what I experienced so far, the game is a nice throwback vibe for anyone who is into Classic 2D Metroid - and is also a good reminder for certain gamers of some of the Classic 8-Bit NES Games That Are Legendary For Their Frustrating Difficulty. No issues with the gameplay & controls here, although I do wish that the character could aim & shoot diagonally.  If Metroidvania is your thing, then you will find something decent about this game.
