From the Steam page:
"The Megapuzzle was only the beginning…
A lot of strange anomalies in GooUniverse have caused the creation of new puzzles that are so insane they could mess up your mind and turn your brain into ooze! New traps, new buttons, new aspects to the game… Can you solve them all using your butter squishing fingers and your quick mind that makes other people jelly? Yes, this was a pun. Take the mission seriously and remember to always goo on. "
