Here's a game for people who LOVE upgrade systems. Nearly EVERYTHING in the game can be upgraded, including Menu Buttons, Game Graphics, and loads more. You even have to buy your own mute button. How fast can you upgrade EVERYTHING? Use LEFT and RIGHT ARROW KEYS or "A" and "D" KEYS to move. Press the SPACEBAR to fire. Menus are navigated by YOUR MOUSE. Note: This game looks terrible until you upgrade the graphics, it's intentional. Have fun!
