Have been experimenting with some different video modes to make the most of the Arduino Micro's limited resources.
Here's an example of a text-mode game, using 8x8 characters gives 20x18 characters on the 160x144 LCD (this could easily be turned into a graphics tile mode as well by replacing the characters with tiles):
The great advantage of text-mode is that the screen buffer is only 360 bytes (20x18) as opposed to 2,880 bytes (160x144 / 8)!
I adapted the game from this source:
