So, I had barely started playing and I had just got stuck and then after a bit the game said goodbye? It was right after the part where you flappy bird down and around an obstacle-- I was trying to figure out how to initiate a moonwalk in midair to continue rightward and I hadn't figured it out yet and either I hopped up to the next screen upwards or I pushed a bad button to push without knowing and that's when it happened.
Went a different way and got goodbyed again :( I think it was the same room a different way. I think that means it's the ending. I heard in the comments there's music! I haven't found it yet! D: I will keep exploring (being careful not to win) and hopefully not have to use the walkthrough but I saw you posted one so I will keep that in mind in case.
Ok, I found the music note. It did not make music :( It did make the cat happy, but I think the expected progression may have been double jump-->flight instead of double jump-->triple jump-->flight like happened with me ^^; because if you have triple jump the only place in the game the music note works it's actually harder to use than just triple jumping up to the ledge, and you're gonna need moon walking either way. Personally, though, I feel like triple jump is way more guessable than music note, but oh well.
