Heya Nicolás!
Since you got me hooked on The Watcher, you can’t stop me from comparing the two as they are similar in mechanics and controls. The first difference I noticed is the improvement in text control. I really enjoy the text continuing step by step (which allows me to read at a natural pace), instead of having a refreshing text box presenting typewriter animation or a simple text block. The movement seems to be a ‘never change a running system’, so I will be sure to pay extra attention to wall collision/pathing this time and will make an edit to this post if I run into any problems later! ;)
