To me, a good Getting Over It requires three elements, 1.) simple controls but difficult movement, 2.) interesting visual design, 3.) a motivator. This game has (1), a little bit of (2), and nothing on (3).
The motivator (3) could be anything, text appearing on the screen, a voice over, some gentle "flow" music. I only played the game for 7ish minutes before falling down hard. With nothing to motivate me to try again, I think it's normal to give up after a few falls. Use a motivator to make it difficult to give up.
Onto (2). I like the variety of terrain physics. That with the movement mechanics allows for a more organic feel to progression. This is probably due to good level design; it's quite good. It introduces a new terrain while you are safe, then adds the risk of falling after you mess with it. I did, however, fall with my first interaction with the bouncy guacamole. I bounced over the safety platform and into the other guacamole platform and kept on bouncing until I fell through. I was a sad :c
(1) I thought the moving arrow mechanic was going to be all the mechanics on this game, but when I interacted with the terrain it definitely made the mechanic more dynamic. Great design on them, and again, great level design.
