This is really cool, I tried to use Love2D ages ago but decided to use Defold instead because I wanted an IDE. It's cool to see people still using Love2D and utilizing it for game jams.
Overall this was a fun game, I like the flow of gameplay. I think it also fit in nicely with the theme. The art was really nice and fluid. I think the message of remembering the cost of materials when you make something is good too.
If you wanted to improve, I suggest adding sound effects and music.
Overall, super fun game!
