Nice! Love the idea, the visuals and the music.

It feels weird to press right to go left when you're on the underside of a box (though I understand why, and not sure what the alternative is). Most of my deaths were due to pressing the wrong direction when I was clinging to the bottom of something. Maybe with more levels I would develop muscle memory for how that works.

Also, I pressed 'feedback' after the end, and when I came back the option to subscribe to the mailing list was gone!

Overall, very cool! Looking forward to seeing more.
