I'll just start with what I didn't like, it's a pretty short list - mostly UI stuff.
On the windows version the icons on the left for components were not visible, so I had to mouse over and read the tooltips. Once you placed a component on the board, it was easy to forget which value the component had since there was no indicator like "+3" above it. And if you mouse over the tooltips too quickly you'll cut off the meter's story conversations. Maybe the component information should've been on its own, like it could slide out from the component inventory or something.
Although the puzzles were fun, it never really got too much beyond keeping a running number in your head. The splitters don't really change how you approach the problem, the dual signal just means start out with double the number. I think as a foundation though, there's a lot of things you could do with the idea, so conceptually it is excellent.
Overall I would say the design and idea are polished and fun, it just needs some technical work and maybe some growth for its puzzles. This was one of those pleasant surprise kind of entries, it was just cute and unique and I'm glad you submitted it!
