Game looks great ! I got stuck the longest on the part before the huge crab.
I did it but i was quite hard, maybe consider adding a easy setting that show the jump trajectory like in angry bird, there is plenty of tutorial to do that out on YouTube along with a separate timer and leader-board. Also when you spam click to make small jumps to re-adjust, it looks quite weird, maybe it would be better to have the player make a step instead. The speedrun timer should probably start when you start your first jump instead of when the game loads. It would be cool to also have the timer for speed-running stop when the player is on the floor not jumping so that way the speed-runner don't have to worry about losing time waiting for crabs.
