Thank you for the large amount of feedback :)
This was my first attempt at writing a (proper and full) story and designing a large set of levels. In hindsight I agree that I probably should've used the text as terrain more often. I found from playtesting that players were more likely to notice and read the text when it was part of the level design. I also agree with your view on the last level. I have heard alot of good things about "Thomas was Alone" but I haven't played it myself yet, maybe I will look into it.
All that being said, I probably won't be changing or updating this game in the future, since I usually am a "finish it and forget it" sort of developer, especially with gamejam games (unless there is a huge bug or flaw). However, I will keep your feedback in mind for future games.
