The game is really cute and works well technically.
What I personally didn’t fully understand is the purpose of the mirrored mechanic. Since both sides are completely identical, you can basically focus on one side without really needing to pay attention to the other.
I think it could be more interesting if the two sides were a bit more different, for example with different obstacles or small variations. That way, the mirrored mechanic would feel more integrated into the gameplay and a bit more meaningful.
