Good game!
At first I wasn't exactly sure how the mechanic worked, but I figured it out pretty quickly.
I sometimes had some issues with guns/projectiles being a little inconsistent, sometimes they wouldn't attract properly or wouldn't hurt enemies when thrown, or they would clip through the floor.
I liked how you were also able to repel enemy bullets by using LMB.
The intro camera animation was also really nice, although the text could be a little clearer (only just noticed the U is a magnet, and "to a" is a bit vague too, could use some lighting).
Overall a pretty good game! Good job.
