Thank you for the in depth feedback!
I definitely agree with lots of these points looking back on the game. I was thinking of rethinking the entire control scheme, making switching and activation keyboard based, (with a UI button for touch screens) and making the player able to precisely control where the magnet goes based on mouse clicks (or alternatively use keyboard controls as a secondary method.)
The magnets should definitely be faster (When I was making the jam build, I worried that would make precision worse, if I redo the controls I don't have that problem anymore.) and they should be able to pass over/underneath each other.
Glad you enjoyed the game from a visual and audio standpoint! And I'm really happy you felt that way about the game feel!
I'll take all your feedback into account when I am back working on the game again!
