Pros and cons are down below) Check out my vid here (likes and subs are highly appreciated)):
Advantages:
I love the concept! It's so interesting and unlike anything I've ever seen before! I love the puzzles you came up with - they were fun to solve and very brain-breaking as well ahah. The puzzles were simply amazing! It felt very satisfying to solve them, though sometimes I would find the solution by luck and then my brain would literally switch off trying to understand what had just happened ahah.
Disadvantages:
1. Some moments were frustrating because it seemed that the square was jumping differently in different levels (though I'm not sure). Each time I felt like I started to predict where the square would land and finished the level, it felt like I had to learn over again. Don't know why. Hope you understand what I'm talking about. That was a bit frustrating.
2. The game is cool as is but it would be so cool if it would have a story and lore. Maybe some 4th wall breaking as well? I think a good example of a puzzle indie game with interesting story is a game called dreader (https://donitz.itch.io/dreader). Maybe this will inspire you to make something bigger out of this cool concept.
3. I also didn't like how background music would abruptly stop at some points.
Overall:
I think that the concept is incredible! I believe that if you'd come up with an interesting plot or, as I've already mentioned before, 4th wall breaking - the game could become legen - wait for it - dary! It has so much potential! I rate it 5/5 as is because this experience definitely deserves the highest rating possible but I hope that you'll continue developing the concept further and make this puzzle game into something bigger!
Hope my feedback was useful!
