It's really hard to tell a story and express with such limitations, but IMHO you did well with the level dessign.

I specially liked the lvl 7and 4. I liked the metaphor that "reaching" someone, could be bad/hurt sometimes (lvl 7), but sometimes is necessary/good to trust in others (lvl 4) for moving on. Sry for my english. 

I encourage you to explore the idea and continue with the game, I'll be glad to play it.

Nice story!
