The concept was a really good concept, and the boxes worked well. I also liked the level design too, it was very difficult
The only things I didn't like was how the movement felt, the movement felt very uncontrollable and it seemed that it just took too long to get up to speed, and the jump felt floaty but it also felt like it was a very small jump, which worked well with the level design which was one of the really good things about it, but it just felt like moving to get to where I wanted to be was very difficult which could've been what you wanted but to me it just felt like it was just a handicap to the puzzles and not in a good way.
So overall It was a good concept, level design was really good, and I thought the art and UI looked clean really well done, but the movement just made it really hard for me to keep going and wanting to play it
