Electroplankton Luminarrow

About

Luminarrow is a puzzle game that uses the Nintendo DSi's touch screen to let players draw arrow paths that guide glowing plankton through levels. The plankton follow the arrows you sketch, so the challenge is arranging them to reach targets while avoiding hazards. Early levels teach basics like direction and momentum but quickly introduce shifting currents and multi-step puzzles. The game's charm lies in its simplicity, relying on clever physics and minimal instructions to let players figure things out. What stands out is how open-ended the puzzles feel. Many levels have no single solution, encouraging experimentation with how arrows interact. A small but vocal community still shares custom level ideas online. While the overall content is brief, the game's elegant design and satisfying "aha" moments have kept it in the spotlight for DSi collectors. Its 2009 release date makes it a relic now, but the tactile gameplay feels fresh compared to modern touch-screen titles.
