Rules

The theme is "Original GameBoy"
Keep the original GameBoy screen resolution of 160px x 144px. You are allowed to scale to viewport, but must keep the aspect ratio.
Color palettes must consist of up to 4 colors. (Only 4 colors can be displayed on the screen at a time, so you are more then welcome to have changing palettes!)
Use the same control scheme as the GameBoy (D-pad, A, B, select, start).
All assets must be created in the duration of the jam.
