The Last Ace is a laid back shooter with a unique scoring mechanic and aspect ratio. The scoring mechanic is based around that for every second you stay alive, you earn five steinguilders (money that acts as points). However, if you are in the bottom part of the screen, the Barnstormer Bonus (BSB) will activate (indicated by the appearance of an icon in the lower-right corner of the screen), giving you ten steinguilders for every second you stay alive. Of course, it's generally more dangerous to be in the BSB area. There are some other surprises too - Check out the readme for more info.
