Judging by demo videos, I think that the UI is not very efficient. For example, let's count how many gestures an user has to make to add an oscillator and connect it to a speaker:
- click "+"
- carefully read the menu, locate and click "oscillator"
- maybe drag the oscillator to a desired location
- click "+"
- carefully read the menu, locate and click "cable"
- drag the cable to the oscillator
- catch another end of the cable, which is swinging and trying to escape from your mouse cursor
- drag it to a tiny speaker's socket
This takes too much time. I believe the UI can be significantly improved. Or maybe this can be turned into a game where the devices are playing against you, jump and crawl trying to escape from you (but you can bind them with cables), and so on.
Also, "+" button is too close to a trash button, and it is easy to accidentally click it.
