I don't understand why many people are complaining about controlling the cube is annoying, I kind of used it to my advantage by tilting it so I can easily get on top from one side and pick it back up when I resume time from the other time https://prnt.sc/susg6g. Also, I'm not sure if this is the intended way of solving this puzzle https://imgur.com/FUX8MWX. If not, then don't change it cause having multiple ways of solving a puzzle is a sign of good puzzle design.
The puzzles weren't hard. All you gotta do was experiment a little and then the answer becomes obvious. Nonetheless I did enjoy experimenting, and definitely had fun playing with the mechanics.
