I love all the different mechanics! The game was constantly introducing new things, and combining them with previous mechanics in interesting ways. I do somewhat agree with the other comment about the puzzles, though - sometimes the solution that ended up working for me didn’t feel all too “intended” or “correct”. The magnet I mostly just used in a straight path to effectively freeze a boomerang in place, as the curving behavior was too flexible to be able to satisfyingly plan a solution around. I’m not sure if that was the intended way to use the magnet, but it made the last few levels a lot easier.
I might also like to see more sound effects; a lot of the game felt a bit awkwardly silent. One for when boomerangs bounce would be a good start, I think.
