Finished Limbo after it was sitting in my library for years and it was really emjoyable. I did not expect to like it as much as I did but the puzzles were all completely doable (

Tap for spoiler

except that one with the minecart and the electric rail grr)

.

Also played through Mouthwashing and was pleasantly disturbed. The lasst 20 minutes get a bit long in the teeth but overall a great experience.
