Fomb's Idle Hands (VIDEO)
This is by far one of my most favourite levels. This was the first level I played when I purchased the Kitty Connect add-on and at the time I thought WTF is this? I just couldn't beat this level at all. I eventually clocked it years later.
When I played this level again recently for video recording/map making purposes, I realised the tree on the right was cut in half so the map was not 100% complete. I had to again replay the level just so I could get a complete map and annoyingly, I clocked the level in almost half the time I did in the video! Alas.
