What a fun little game. I'll admit I was worried with the wall of text at the very start, but it turned out to be a fun and well rendered platformer. My once criticism is that beeping noise that starts when your time gets low. Maybe replace it with something more pleasant to listen to or make it last for a shorter period of time.
Edit: maybe one other thing. I know the concept of this game is to get from the starting point to the goal within the time limit, but I'm finding that this ends up with me spending most of my time replaying the same easy parts over and over again with very little time left to practice the harder parts. Maybe if there was an 'easy' mode where the player could restart at checkpoints it would help.
