Ah man... OK listen, I just tried it myself after downloading it from the page. It's letting me play the minigame fine X'D Could it be you are using the wrong input with the arrows? ~__~ Remember: it's right-left, up-left-right, and up-down
No. I know how to press arrow keys. I've confirmed multiple times through multiple playthroughs that the minigame definitely either throws an error or hangs after the first couple of moves. You may do with that information what you will.
