The game was good, you came up with a very unique and fun concept! I have some remarks to make though:
One gameplay bug (or unintended feature) was that I could simply hurl over all the items until all items are there, including the required ones, so I get to proceed.
The music was good, not repetitive at all since there were multiple tracks!
I would have liked some sound effects for picking up items and dropping them. Maybe also for when they collide with one another.
Some polish on the physics system and picking-up system would have enhanced my experience as well.
The visuals were slightly displeasing due to the lighting slowly stabbing my eyes (just a bit though).
