Now that I've seen the intended solution, I'll definitely recommend not holding back on skipping the levels that are off the required path. For example, I think you may have a slightly easier time with the level if you had moved on and played through to "Moonwalker", which is on the required path (right after the "Hypercube" mid-point boss level), as there's something somewhat similar towards the end on that level as well, but there they actually give you an "H" hint on the move. Being able to apply things you learn later to earlier levels you may have skipped can be very helpful with the purposely harder levels that are off the required path.
In other cases, non-required levels may feature things that are difficult in ways some people may not care about (*cough* Project Orion *cough* ), so if you force yourself to hold back on such levels it can greatly diminish enjoyment.
