Seems like I've reached the limit of my smarts/ingenuity/patience at around lvl. 20.. 22 has got me totally stuck too.. Read your hints and yeah, I can get the right and centre into the RH portal but can't see how to get the left 1 into the LH portal or the contents of the other out of the centre island.. ?!.. EDIT: and yet I just got lvl. 23 reasonably quickly (15 mins?) which you consider tougher (with the aid of your hints admittedly)..
