I liked the concept of this one very much! The moment -that thing- happened, it completely felt like a Stanley Parable moment, and I loved it. I liked the little story arch you had going here as well, although at times it was  a little hard to understand with how quickly text would fade out, especially when text was displayed at the same time as learning a new abillity.  There were some things I'd have appreciated, like a checkpoint system (but because of the time limit, it's understandable it's not in there), and the ability to sprint-jump (this could possibly make the leap useless though.) I think you did a lot here with the time you had, so good job! It might actually pay off to do the same amount of work, but cram it into a smaller world, so the world feels a little more 'full', if that makes any sense? But not that I minded that too much! Overall cool entry, and you definitely went for a very ambitious project here!
