Wow, thanks a lot!!! And many thanks for your suggestion on how to ease in new players without boring veterans, I´ve been trying ways to do it but couldn´t find anything. Your idea is just what I was looking for and it will be very easy to implement!
You´re also right with the controls, Ctrl/Shift was such a bad choice to make as Shift poses problems for Windows users and Ctrl does so for Mac ones. After the voting period ends I´ll update the game with different default controls, configurable keys as well as your awesome method to ease in new players.
Thanks a lot for your feedback, really :)
