Dark

This simple homebrew game was made with Family BASIC on a Famicom console.

Walk around the level and get the flags before the walking ball can get you. Pay attention to where everything is because as soon as you get the first flag, the screen goes dark and all you see is you and the ball. The ball that is always creeping closer to you. Find a flag and you get light. For a brief time, then back to darkness. Multiple levels and 3 lives total.
