Some of these later levels are ridiculous... Listen to this one: "Balls come in from any direction. For the first ball nothing comes out. For each ball after the first, the previous color ball comes out on the opposite side of where the current ball came in."
I like this one. I think my solution is pretty. It was worth 2 stars, and it might be 3 stars if I could just find the 3 star solution to #48. I have 3 star for #47 but only 2 star for the reset, which is what I need for Storage 1.
#59 is destroying me, all the more because I know it's the last one. I feel like I'm very close (with a ridiculously inelegant solution) but there is just some little bug somewhere I can't find.
If anyone is curious as to what #59 is,
it's a stack. Red and blue balls enter from the left but have no output. Instead, they are stored in a stack. A green ball will pop a ball from the stack and output it. If the stack is empty, a yellow is output instead.
The example input output is:
rbbggrggg

I think my most hilarious solution so far is for #56. 271 tiles! It's because I used a previous solution as a custom tile and then I duplicated it with minor changes... not to mention overuse of lots of spinners that could probably be simplified with splitters and arrows.
Feature request: a shortcut for rotating or mirroring all tiles on a board. Would be nice for custom tiles.
