Power the bulb

Power the bulb is listed here under Puzzle. There is no launcher and no install between you and it. Taps and swipes are the whole vocabulary — a phone plays it best. Its tags here are arcade, casual, click, hypercasual, puzzle.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Nothing is saved to an account, because there is no account — progress lives in this browser.
