HINTS (only read if you're stuck): It seems like the keypad puzzle is giving some people trouble. Here are a few clues. It seems like there's a major emphasis on colors. Remember back to 3rd grade art class:
Red + Blue = Magenta
Red + Green = Yellow
Green + Blue = Cyan
Also note how many sides the shapes have. This is important.
This is the first chapter of my new game, Brain Scrubbers. It is a point and click adventure game, emphasizing on puzzle solving. Sound is currently not implemented to save on file size. If you need help solving a puzzle, let me know in a review and I'll respond with the solution. You should be able to solve it on your own though. Have fun!
