make button presses easier to handle

[cutierobot]

in relation to #4, At the moment its easy to think you pressed the enter button but in fact, you haven't I propose the current implementations to make it easier to notice if you have actually hit the enter button:

• [x] change LaunchButtonbutton colour from black to red when "enter" button is pressed
• [x] if LaunchButton black and pressed, play a tone that indicates fails or no or something
• [x] if LaunchButton black and pressed, flash enter button 🚩
