Hi Matteo!
The learning curve is perfectly smooth and you introduce new mechanics seamlessly and intuitively. For example, I didn't need any clues that boxes could be pulled, because in the previous level you showed me they could be pushed, and in the next you gave me one that was impossible to push! So naturally I got pullin'! A true disciple of Mark Brown!
Thanks for sharing, good luck in the jam!
