B.I.O.T.A.

It's a forgiving Metroidvania that doesn't surprise all that often, but hits the spot for platforming fans and those who enjoy carefully considered backtracking. I'd also say it's not a bad starting point if you're looking to get into Metroidvanias but don't know where to start. It'll teach you the ropes without overwhelming you, with plenty of room to save and switch things up if you're struggling.
