I am very surprised I got up in the middle of the night to make a game in (pretty exactly) 0 hours. And even more surprised that I actually finished (well kinda)! I used all the time until the very last second. I didn’t manage to export it in time, but I don’t think anybody would consider that cheating… Here’s a screenshot and a time lapse video.
Play the game here [JAR]. Move with the displayed keys to eat green bits and avoid red ones. Losing ends the program.
Luckily, I didn’t lose any time, since I got to experience this hour twice.
