I finally got around to playing this game! My thoughts:
Really fun, interesting physics, relaxing music, beautiful design and quite addictive! It's quite challenging initially, then just as you start to get good the levels and puzzles evolve and the physics changes to make it more of a challenge again.
There are a few small things I disliked, such as occassional small bugs where you end up trapped.
I enjoyed the dark space level towards the end where the gravity is reduced and the addition of the color glitches was cool, however at this point the game become a bit more stuttery. It wasn't smooth and I had a couple of crashes.
I HATED most of the last yellow and pink level where the jelly surfaces are glitching like crazy. This bit went on way too long and felt like it was pure luck whether you would get to the next window or not.
Once I got to the end I didn't get any credit sequence. For some reason I just got a blank screen. Another bug?
Side note, I only found 3 or 4 of the computer terminals and have no idea where I should be looking for the rest.
Overall though, despite being frustrating in places, it was an enjoyable experience!
