Quite liked the mechanic here, probably my favorite interpretation of the "weighing scales" concept. Simple, straightforward, and relatively engaging.
I think the difficult part here is depth perception and getting a good sense of what may or may not collide with the scales (or wings); I think having a bit of adaptation and learning there is good for the core gameplay loop, but I feel like perhaps the angled view of the playfield made it a bit tough to understand where things were vertically.
Great interpretation of the theme, good work on this!
