Played it cold on the itch page, mouse, a few minutes. First fall at about 25 seconds, then I went back in and played it through to the finish.
No music, no sound at all – that was the first thing I noticed, and it made the first ten seconds feel emptier than the jumping itself does. The dotted arc while holding is the whole game for me: once I trusted it, I stopped looking at the platform marks and only watched the arc. What read as thin: after a fall I wasn't sure whether the number I had reached was gone or kept – a one-line "best: n" on the start screen would settle that. Very simple build, but the one verb is honest and it works.
Thanks for the notes on Meteor-Dodge, all three are on my list.
