Cave Story for Wii Ware

An absolute masterpiece! Fantastic gaming experience that I thought had gone the way of cartridges and wired-controllers. It looked 8-bit, it played like a 2D Metroid game (gameplay that was very reminiscent of Super Metroid), and had a sometimes quirky story. If you like Metroidvania games, then you'll ABSOLUTELY ADORE this game. I can't recommend it enough. Download it and play it!

My only complaints are that it's far too short, I want more! And there was no exploration percentage of completion at the end, like there is on Metroid games. I'd like to know how well I did. I ended with 30 missiles and 45 life energy.

Are there any sequels/prequels?
