Hi Kevin,
I'll be totally honest. I LOVE all TIM games that marked my childhood and I LOVE the main Contraption Maker game. I created hundreds of puzzles myself and it has been one of my favorite game collections.
Therefore, my disappointment with the latest Incredible Puzzle Pack DLC was bigger. Literally 99% of the puzzles can be cheesed by using just one or two parts. It can't even be ignored because some of them are actually intended. Announcing that DLC as an homage to the original game and then offering such a bad untested pack is really disappointing, especially after such high standards...
