I guess you have played Pixel Art Maker by ROSMan, so I'll just say the instructions are the same as for his. DRAW
This game is completely coded by ROSMan. I edited the thing to be bigger. You now have 28 x 40 pixels of space to draw! The 'Get Code' and 'Use Code' buttons still work, it's just that the code is too long to be posted in the comments. Derp.
