i keep being really intimidated by composite metrics but then i have by far the most fun on them. i don't know what makes a good sum solve: the leaderboards have most of em in the 300s, but this has both the stupid expensive wheel and the stupid big input, so i'm not sure what to do about that. still, something can probably be done about that big swing (i tried building on top of the input but it added 20 cycles and only saved 10 area). maybe you could cut another arm, but i think the biggest improvement can be made on cycles.
