Yes, that is what I mean by "not good". Also Shift+RMB is very awkward. E.g. 'Q' and 'E' or 'Z' and 'X' would be much better. Having all of those options to be open is even better.
Regarding the timer, I mean why not just have a "Send packages" button without any timer. It is a puzzle game. Nobody likes to be on a timer when solving a puzzle.
