Super polished! Simple graphics and sounds, but everything is really clean and nicely done. I'm not usually into this type of game, but I could tell the execution was really well-done for the genre.
I did find that it took me several tries to actually figure out how the magnet works, but honestly I prefer it that way; figuring out how how to use all of the pieces to achieve your objective is the entire point of a game like this.
All around, everything that someone could hope for from a jam game! Nice work!
