yes, because the floppy menu has the option to prevent "down" to work. I have removed it now.
Nice. Activating the shield with "down" works now. Was Fire2 for the shield now completely removed?
By the way, when i played the game longer, i had it a few times, that the parts of enemy sprites, that had already been shot, were not always completely removed from the screen immediately. It takes a while and then, in isolated cases, you can still briefly see a part of an enemy, that has already been killed. Happens not often, but happened a few times here so far. Apart from that, this beta-version plays well, already now. Looking forward to the final release.
