Brutal! I figured it out though. If you click just barely in front or behind you'll very nearly jump in place. Once you got that down it's just a matter of edging into the correct location to line up your jump properly. A bit of a learning curve but fun once you crack you. Usually not a huge fan of those "rage" games though, usually about climbing or jumping ha.
So how much of this was intentional from the outset? Did you truly intend to make it this difficult from beginning or did you just get to that point and then figured it was better to fully finish it than spend a lot of time tuning the jumping. How early in the process did you decide on two jumps?
