Looks like it could be a great concept. As is, I like how the level design allows for a few branches to get past obstacles. I'm curious to see how the polarization pickup mechanic can create more obstacle variety/encounters. It seems ripe with potential for puzzles a la games like Mighty Switch Force. 

This a neat idea! And a good interpretation of the theme, love me some magnet science :D Nice job! The jump mechanics also felt nice and smooth!

I like your idea.  It's a very interesting platformer.  Couple of of bugs with the background but besides that it looks nice.  Good job!

I do love  how there is a variety of options in how you can go through a level as well as potentially many challenging variations (like speed runs, pacifist runs etc.)

I feel like it would have been best to have the option to manually switch magnetism instead of with items , but other wise this was a fun concept!

I really liked that your team made a custom engine and the game is engaging!
