I understood your points. 1) The jumps can be completed. 2) You like it for the challenge. 3) They should consider going back and cleaning it up, but it's still fine to you either way.
No problem. What I was saying is basically my bird's eye view, which is: For the devs to expect players to jump primarily on invisible collisions to progress is beyond stupid and insults their players. I never thought it was possible for any game dev to think this was acceptable just because it could be completed. Until now.
