This was a wonderful experience! I absolutely loved the aesthetic and theme, and the music was also on point. The mechanic was simple yet oddly relaxing, and it overall felt very original! :D
I managed to block myself off from being able to continue climbing because I placed a larger object above my head - it might've been nice if the player were able to pick up something that they had already placed. I also might've wished for the extend-o-arms things to be just a tad quicker; I enjoyed the slow, relaxed nature of the game, but the arm-extension seemed to be just a bit too slow.
Nice work!
