Good art. Good music. Controls didn't seem very intuitive but I read below you aimed at a German keyboard. I had to keyboard-mash until I found what worked. I also couldn't explicitly select a type of attack, but I'm guessing that's more to do with key mapping. Needed to Alt-F4 to exit, heh.
Neat idea. It could be expanded upon to stop different eldritch beasts of varying sizes and powers. Good efforts from the team!
