Logic Gates - Electronic Simul

I like how the app works because it lets me to create my own integrated circuits (IC) and use them to create even more complex ICs. So I thought it's worth buying the ad-free version to support the developer and I did. Though, the only things I want this app to have are (1) feature to export diagrams as images like png, jpeg, etc., (2) feature to copy/paste circuits/gates and (3) be able to add gates quickly or add multiple gates at once.

I just mest around with this and i got a cupple things to say. 1. The wire color when its on and off is to close, if the color was gray when off and red when on that would make it better. 2. A hot bar somewhere on the screen that had customizable inputs like, an AND gate, or an IC you made. Just anything like that.

the game seems great.. until you get to level 19 and the logic becomes faulty (help!) EDIT: thanks for the quick response, I spent a long time on the level because I mixed up the or and xor gates in my head which led me to believe that the game, rather than my own thinking, was faulty . Apologies for the inconvenience, I've now corrected my review to five stars which I think the game (and also the customer support) deserves. Thanks!
