Cute story. Sweet but weird. I love the ladders. It might be cool to have one really hard level after he ditches his friend to convey the burden of loneliness.

Reminiscent of Thomas was alone, which is a great game. I like the simple, easy to grasp narrative overlaying the puzzles .

The narrative structure is really what glues these puzzles together. It makes the shortness of some of the levels intentional for story pacing, and the introduction of new mechanics relevant in more than a gameplay sense. If anything I think you can take this farther to teach mechanics through what one might expect from reading the intro dialogue (You do a little of that already, this isn't a criticism more of a supplementary idea). The only issue I ran into is that I couldn't tell which enemies would run after the buddy or only run after me, I think they had the same sprite. That only was an issue in one level though. Great tiny game!

Again, I really like how strong the narrative was in this and how it drove the puzzle.  Im just impressed how much of a story you could tell in puzzlescript. 

You always manage to build really solid, small narratives, and this is no different.  I like how you used different mechanics to tell it especially at the end when he realizes maybe he doesn't need his friend. The only thing is that it's not always intuitive what we're supposed to be doing. For example, jumping. That being said, I was able to figure it out relatively quickly. Great job!
