Impressive what you managed to deliver in those eight days. It's quite funny to see another assembly game, and yours is so cool (the screwdriver sfx is so satisfying). It took me a little while to figure out how to replace the comb and screws, but once I figured it out, it was quite enjoyable. I don't know if this is normal, but it's a shame you couldn't add music to thank the player for fixing the music box. Also note that sometimes, depending on how I place the plastic cover, it follows the screen movement and stays in the middle of the scene (maybe a bug?).
In any case, congratulations on what you've produced.
