Logic-Gate-Design

The app is useful and helped me understand logic gates. (Btw anyone who is having trouble, you have to hold the button)

I put a review here complaining about this app, and they responded with helpful information about how to use it.

When i first played i was really confused using the help menu on things wasnt really helpful for instance: deleteing a gate that went off the screen, i looked in your help menu and it said hold down a delete button. where would that be? it doesnt tell you, so after looking around i figured out you scroll the little menu at the bottom the logic works fine enough for me so thats good. what I would like to see is a little navigation tutorial and maybe arrows on that little menu on the bottom so i know theres more options i can use.
