Would be helpful to note the controls, I tried using the arrow keys at first, but that only let me move left/right, before I tried WASD and was able to make forward progress.
Really interesting concept, I like the idea. I think it'd work better with tighter controls, right now you can easily get stuck and fall between places and then just not be able to jump any more. I think it'd be better if you just hit the direction of square you wanted to go to left, right, diagonal left, forward, diagonal right, and just jump to that square directly (maybe with long hopping if you hold one of the keys down), leave the fuzziness out of it keep it to the logic of which is the safe square to jump to?
I think I got to about 30 in one run, but that was with some scooting along the top for the last bit.
