To be objective I think this game is pretty good, the concept interesting where you control a cursor to move around the blocks. The whole idea of claustrophobia - the cursor getting in the way of the player and trying to get them out of the way is pretty fun. The vibe is pretty good too, I like the visual effects and sounds, really gives those retro puzzle game feeling.
I guess as a fan of hard puzzle games who played a lot of sokoban-likes, I just can't help but feel that this is like a well thought of variation of sokoban - feels different but quite similar to the core. Not sure if it's the level design or just the mechanic itself, a lot of the levels follow a similar pattern - use the cursors to move the blocks to some place, then find some crevice to get them out of the way. Playing games with several player characters have definitely gotten me used to this kind of movement too. Probably cause of that, I felt that I was moving more than thinking, in every level trial and error and moving "what feels right" I could solve the level
