Great level design! I love how you introduce each component first, then make me use it. That's solid game design right there.
I would have liked some harder maps though. Also, I think the keybinds could be adjusted. Having pickup and reset on distant buttons feels awkward. Maybe mouse left/right clicks, or put them on J and K? I understand putting reset on R is intuitive, but right now I'm using my left hand for all the buttons while my right hand does nothing.
With better keybind placement, you could probably add more precision to the reset and pickup mechanics as well.
Overall great job though! Really cute SFX and art style.
