Prince of Persia TLC is an excellent game, but I do think it's a little too long for a Metroidvania (took me 25 hours to finish). Apparently it's made by the same team that did Rayman Legends! Also, Streets of Rage 4 is one of the best beat-em-ups I've ever played, so I definitely want to hear your thoughts on that one when you play it! 

I played Tunic on Switch when it first came out. Excellent game! Unfortunately it got too hard for me, so I never finished it. But it does a great job of letting you freely explore, just like the original Zelda. 

Yes! Hades is so good! I'm not a fan of rogue-likes, but Hades is the big exception, and I'm very excited to play Hades II later this year.
