I finished off the last two chapters of World of Goo tonight, and as expected, chapter 4 had a rather ‘virtual’ twist to things, adding a bunch of new goo types and things like blocks and slabs. The epilogue chapter was fairly short, consisting of only three real puzzles, but they were much harder than the others. I didn’t have to use any more skips, but I did have to consult some hints on a few of these later levels.
All in all it was a rather interesting, well-done puzzle game with a lot of style. I don’t think I’ll be going back to try and get the ‘OCD’ ratings on each of the levels though; I barely scraped by on most of them as it is…
