I beat Cave Story 3D (3DS) on normal difficulty, with the true ending.
This is a massive deal for me. I was first introduced to Cave Story roughly three years ago, when I saw the 3DS eShop version (the one with the original graphics and music, but the features of Cave Story Plus). I beat the game with the normal ending and made the prerequisites of the true ending, but I was nowhere near as good of a gamer as I am now, so I just couldn't beat it. So I gave up on it. Now three years later, albeit with a different version of Cave Story, I finally got the true ending. I'm really proud of myself, and really happy I gave the game another chance. It's actually really cool despite the criticism (I never understood why people complained about Nicalis's "bastardized" Cave Story ports), and the graphics and music did a great job capturing the dank, moody atmosphere. I'd love to see a 3DS Metroid game in 2D, but with 3D graphics like this one.
Edit: Forgot to mention that my playtime was about 9:30 according to my 3DS log.
