Hey, full marks! This game was such a neat treat. The puzzle idea was neat, not super complicated, but you got a ton (hehe) of mileage out of it. I especially loved the relative weight visualizations. Both really helpful visual cues for what needs to be fixed and really fun comparisons. "Oops, I accidentally weight a coin against THE SUN. Also I guess that's on the order of magnitude of the weight of the sun, good to know." Really fun, really liked it. Once I got a puzzle mostly solved I sometimes brute forced the rest (eg. one scale is done, the other seems like it fits, I'll just move some zeroes around until it works), but mostly I just felt proud of myself when I got it right. Having some intuitions about the scales helps a lot with ballpark organizing the pieces, then it's just sort of toiling about until it actually fits. I really enjoyed it, I think it's my favorite game so far this jam.
I only have two (relatively minor) notes:
The mechanic where you click to flip the value of the boxes felt a little too hidden-information-y. I felt like I was being forced a little to brute force the solution because there were so many possible combinations, not all of which were possible, and it was too much to keep in my head. I still did them, but usually I spent more time trial-and-error-ing than actively solving the puzzle.
Also, I wish there was clearer signage for what the letters represented. I had a sense of what they all were, but especially because there were boxes with the same letter in different colors/cases, I found myself checking that modal a lot and trying to remember which was which, which interrupted my train of thought. I think a scrollover tooltip would've made it much clearer/easier to work with.
Thanks for a great game!
