I really liked this, it feels playful and explorative just moving basic blocks around and seeing where they land. The notepad setting is nice and simple and would leave so much room to have fun with expanding the mechanics/movable block types.
I like the dynamic feel to the camera, but would love it to be more focussed on the puzzle/room at hand so that once a challenge is overcome, it feels like I have moved to the next screen over and made progress. The art style is great and it's a shame when the camera isn't fully showing off the charm you have created. I'd definitely return to this if you made more, well done on getting this to work so well.
