I enjoyed this! The controls got to me a bit (r felt a bit out of place with j/k/arrows) and the timing could maybe be a tad more forgiving on making platforms. The vibe is pretty choice!
I'm not sure if there was supposed to be a cinematic at the end when I found the family or not; I seem to have gotten stuck in a loop running (can post a vid on request if you don't know what I mean.)
I think if you iron out the jank-potential in the core mechanic the experience will improve about 100%.
