Retrospective is great. It is good you can skip the skritt tunnels near the end these days. Was my only critique. Very clever to go through the whole map. Wish we had something like this these days.

My favourite is the whole Super Adventure Box if that counts. ;) Really liked the look at world 3 and i hope they keep adding more next year.

I think the whole game has very nice jumping puzzles tho. Even the hard ones are doable if you cheat with TaCo markers.
