Interesting game although I couldn't get very far (couldn't make those two block jumps).
I don't think I've heard of the phrase "coyote time" but I think I've encountered it before. Often enough to mess me up on games that don't use it. I guess that would explain the one time I did make it. I thought I was seeing things since I swear I was falling and THEN jumped over.
Thanks for sharing the game with us!
Edit: Yeah, that's definitely what I saw. I tried again and managed the first jump maybe 25-30% of the time but never twice in a row to make the second one.
It's very likely just me (since I kept getting very close) because I simply can't do fast and precise at the same time consistently. I would almost guarantee that a frame-by-frame would show that I'm pressing the key very inconsistently with regards to timing.
In all seriousness, I would say to wait and see if you get any complaints.
