Great concept! After failing once, I managed to escape in 2:46.
You've already got comments outlining some of the bugs, so I won't go into that. A crafting game is an ambitious project for a first game, especially with only a few days of dev time, so props for pulling it off! If you were to expand on it, I'd say some enemies would be a cool addition.
Overall great job! Looking forward to playing your future creations.
