Bit Invaders

Bit Invaders is a classic game reinvented for binary number. Every spawning cat has a decimal number, the way to defeat them is to enter the binary number of their counterpart. The game has 10 levels to begin with, plus a endless challenge mode after clearing all levels. There are also bonus scores for speeding up and hiding the binary hints. In endless mode, difficulty will also raise as the game progress. MEOW!
