I see the vision, but I think this game needs a bit of that platformer polish like reducing the hitbox of environmental threats to be slightly smaller than the sprite + adding "coyote time" (where you are given an extra 2-5 frames to jump even after your character has left the platform. I think adding those two would've drastically improved the feel. Also it took a while for me to figure out how to use the magnet, so adding a Control scheme to your game's page would help a ton!
For the positives, I love the art style, it's simple, easy to read, but engaging. The feel of really getting familiar with the jumping felt kind of like a souls-like where it's difficult and punishing at first but as you get more and more familiar you get to almost a speed-runner state where you progress further and further without much difficulty. Overall great game!
