Propeller-chan

In the beginning, the world was not turning.

Propeller-chan is a 2D exploration puzzle-action game built around a single idea: wind moving matter. Spin your propeller to blow air forward or suck it in, and use those gusts to solve the puzzles and set the world's machinery turning again.

★ Steam key included

When the Steam version launches, everyone who bought the game on itch.io will receive a Steam key at no extra cost. Your key will appear on your itch.io download page.

If this offer ever ends, we'll announce it on this page in advance. Anyone who purchased before then will still receive a key.

■ Features

• A world that moves with the wind — sand, water, and smoke, simulated cell by cell. Blow, suck, and watch the world respond.
• A world to explore — a connected map dotted with fast-travel flags, hidden routes, and secrets.
• 1-bit visuals — 1-bit monochrome built from hand-crafted dither patterns.
• Collect floppies — find hidden disks to unlock new 1-bit palettes and transform how the world looks.
• Collect lost files — gather the lost files to recover the forgotten memories of the nation of rings. Assemble every record, and a hidden truth comes into view.
• Three languages — full support for English, 日本語, and 한국어.
  • The English and Korean text will be proofread by native speakers, and the improvements will be delivered in a free update.
• Keyboard & gamepad — play however feels best.
