Wow, that is a large comment! I'm really happy you liked the game so much and I appreciate the feedback a ton :)
I will be making a non-jam version at some point in the future. I've already planned some of the things I want to include and improve upon, but feedback and new ideas are very welcome. I'll also release some quick bug fixes to this one. If you have any suggestions you would like to see in the game, feel free to share them.
The little duck in the color picker is a custom marker I added to its theme (a godot resource used in control nodes). The money clipping out of bounds was a result of me thinking collision calculations were lagging the game when they spawned (so I disabled collisions for pick-ups, but the lag was acctualy something else). I'll add item magnetism for sure, it is a satisfying feature for sure :)
