Line Color 2D

Line Color 2D is catalogued as Puzzle, with 2d / arcade as its leading signals. After launch, confirm the objective shown by the game instead of assuming every title uses scores, levels, or races.

The source instructions for Line Color 2D explicitly mention: arrow keys. Device support for Line Color 2D is not confirmed in the catalog; rely on the controls shown after launch.

For the first Line Color 2D attempt, observe one result connected to 2d / arcade: input response, failure condition, or progress signal. Change only one variable on the next attempt.
