I'm not going to lie, I was genuinely confused on what I was supposed to do. It wasn't until I had the level rotated in a specific way while moving that I figured out the core mechanic. I think adding some instructions to the description of the game would be really helpful, because I almost stopped playing thinking the game might be broken.
That aside, the mechanic itself is really smart. Once I realized what you were going for, I thought, "Wow, that's really freaking cool!" The graphics are really cute, but the white can blur a little too much into each other, making readability a bit difficult coming from someone with an astigmatism.
I really like what you did with your game and think just a bit more polish would make it even better since initial user experience is important.
Good job dev ⸜(｡˃ ᵕ ˂ )⸝♡
