Good news: I can play it up to the first repeat. Still good news: I learned how to play the trill, how t(h)rilling! Because even in my short version, there will be eight of them.
I'm not going to learn the rest (any time soon), because I still need to smooth it out, get it to sound like actual music and (arguably) most importantly: speed it up. I mean, 50bpm is not exactly acceptable for something meant to be played allegro, right? Right ๐ But you can count on a recording, that much is certain!
