Tried to play this.  Gameplay didn't seem very functional - coffee cups tip over too easily, triggering a game over.  Graphics look kind of stretched and smudgy, and the UI buttons were below the window, but the color palette looks nice.  Music is very quiet, but the coffee cup sounds are functional.  Game does not make good use of the resolution restriction; when I launched the game it ran at my monitor's native res and at 16:9 aspect ratio.  Text was very high-res and not within the 64x64 limit.  Sprites were also stretched in a bilinear fashion, beyond the 64x64 limit.  Keep trying, though!  It's a good concept, just needs work.
