Cheers. Which keyboard are you using and which keys would you prefer to have? I'm asking to take into account later on.
I use the Swiss-German layout. I just noticed that I was jumping with the Z key instead of SPACE all the time. ( Z J K )
At the beginning of the game I saw the hint with the key assignment. But I wondered how to use the _ to jump. I didn't try it and I was convinced that somebody used Z X C as action keys again. :-)
