Nice concept! The way to use text as actual terrain was awesome. To just use words to directly "write" what something represents, combined with the ASCII style that's otherwise extremely abstract, made the game surprisingly detailed. For example that the moving platforms representing different vehicles brought a logic into the platforming element to WHY I am jumping around on these things. Platformers otherwise have a very "its moving blocks, deal with it" approach to the reasoning to why you need to jump on stuff.
I would however have liked if you where a bit more consistent with using the text as terrain, as some levels you just had it placed in the corner or in a box. The charm of using text-as-floor with a platformer (I feel) is that you make the player "read" the text as he walks over the words (or at-least encourages them to). Placing the text on a random spot just to be read makes the player instead have to: stop, read, then continue, and it just disrupts the flow.
Also, cant say I felt much for the story itself... I get that its a take on a journey and the notion of "home", but it honestly got a bit lost on me forwards the end. I would highly recommend the game "Thomas Was Alone" for a take on story-told-directly-in-platforming-levels, it has flaws, but your able to follow the story quite well.
Lastly I am sorry to say that the platforming itself left a lot to be desired. The controls/movement could use a bit more work, as right now it can be a bit wonky trying to land on a moving platform. Otherwise it is the levels themselves that need the most work, while most are ok (you are working with very few platform-tools after all), the more challenging ones need a better start layout (especially the last level before the end). When making a level where the player has a high risk of dying over-and-over, I feel that the how the level restarts is very important, so that there is no wait time for my next try. Example: The last level had the issue with the moving platforms being miss-timed, so every time I restarted I had to WAIT for the platform to make a full back-and-forth run before jumping. This made me frustrated not at the platforming part, but at having to wait every time I failed.
Overall, great job! Cheers.
