Wow! I like the graphics - the effects look cool, the monsters are really scary, the music is great, sounds are good too, everything works great. It is not easy to remeber which key to press - not very convenient to switch between "Ctrl" to "B" in one line.
One more thing - is it a bug? I seem to have lost the lives and it says "Try again" I still can press all the shooting buttons and move but the "Try it again" faded screen is above the game. I try to press "Space" and "Enter", how to restart or continue, please?
