Cave Story is a metroidvania platformer with the amnesiac soldier Quote finding a city of rabbits called Mimigas. There's a fan-made genesis port, which you can play online (here)! I've been playing the freeware version in study hall and it's fuckin awesome. Fun story, I've listened to the soundtrack of this game many times over before I ever played Cave Story. One of the most emotionally memorable soundtracks I've ever listened to, and some of the absolute best in indie games ever. Every single song is filled with so much passion and love. The mega drive port (github) has custom music as well, and it's really fun hearing all these bangers with the blast processing vibe. This alone is enough to play the port if you're a Cave Story fan, but everything else is done really well, too! It feels official. I've heard bad things about Nicalis, Cave Story's publisher, but I don't know enough to know where to put my money, and my friend Sam just finished it in class, so we've been playing together and having a good time. It's very well designed and fun, I'd highly recommend playing through it. What's really cool about this game is that it was made by one fucking person: gorgeous pixel art, incredible music (as well as his own soundfont and file type), game design, programming, EVERYTHING! Studio Pixel did it before Toby Fox believe it or not! And it pioneered indie games
