I feel like our fundamentals (squares/boxes and puzzles somewhat involving physics) were similar but we went in different directions :D
Lovely entry, it gets a lot right. The level design implicitly and explicitly teaches you about the mechanics (an explicit example is the downwards arrow, an implicit one is when arriving in the area that asks you to die to solve the puzzle, it because a recurring piece of solving the others after). Aesthetically very pleasing, excellent interpretation of the theme. I fully enjoyed my time.
