Play Urusei Yatsura - Lum No Wedding Bell (japan) Online

Urusei Yatsura: Lum no Wedding Bell came out for the Nintendo Entertainment System in 1986, developed by Yutaka. It was part of that wave of Japanese releases that never made it overseas, so you had to rely on fan translations or just figure it out. The game is based on the popular anime and manga, so if you knew the characters, you were already a step ahead.

You control Ataru Moroboshi, and your main goal is to find and marry Lum, the alien girl, before the day ends. The game plays out screen by screen in a side scrolling view, and you explore the town talking to characters and collecting specific items. A key mechanic is using the items you find on the right people or in the right situations to progress; sometimes you need to give a gift, other times you use an item to solve a small puzzle. The day advances automatically, creating a time limit that pushes you to move quickly. It feels like a race against the clock in a familiar, cartoonish world.
