@konpeito0122 You'll never guess mine!.. Jokes aside, the interesting thing about the Cave Story Beta is that it was close to completion, with Pixel stopping near the end of the game, and the final releases reuses a ton of assets in interesting ways. Here's music+art https://t.co/PDiXDKEFyQ
I know a lot of people find the alt cover of Cave Story + to be better than the launch cover, but I like the launch one a bit more since it reminds me of some of Pixel's art styles mixed into one.
