I'll come clean, even though the double pendulum motion is not random, as I say in the game, the initial conditions for most pendula are randomised. That can make some jumps quite challenging and possibly downright impossible. I didn't want to go into too much detail about that, as I felt reiterating the "random vs. chaotic" element too much would get annoying to the player so I didn't mention the randomisation of initial conditions. Not because I was trying to hide it or anything. 😂
All that said, if you replay the game it may be so that the jump that was difficult will be more doable next time. 🙂
Thanks a bunch for taking the time and effort to play and even comment, much appreciated!
