Thank you very much for taking the time to play and for your thoughtful comment!
You’re right — in the later levels, there is often only one correct combination to reach the target weight. I designed it this way on purpose to encourage players to think carefully and eliminate unnecessary items.
About the visual balancing: that's true as well — if there are no items on the opposite side, even small objects can cause the scale to tilt sharply. It’s something I’d love to improve in a future version!
If you enjoyed the concept, I’d really appreciate it if you could leave a nice rating too, it would help me a lot!
