Thanks for your comments. I 'm aware about the problem with "d"+"space" on dying. First i used the cursor to click on"retry" or "exit" buttons but the last level asks you to be very reactive. You lose time while changing your hand from mouse to keyboard. That's the reason why i decided to use the "only keyboard" method. I had the same problem as you while testing but i didn't realized how to change it before the end time for the jam.
