Made for a keyboard

This device does not seem to have a keyboard and mouse. The demos have no touch controls and have not been tested on phones or tablets.

This window is smaller than the demos were tested at.

Install and run
1. Extract the ZIP and move Meadow Run.app wherever you like.

Android 7.0 (API 24) or later on a 64-bit ARM or x86 device. On-screen touch controls; a keyboard or gamepad also works.
Install and run
1. Download the APK on the device.
2. Open it. Android asks once to allow installing apps from that source (your browser or file manager); allow it, then install.
3. The APK is signed with MicroEngine's demo key, so later demo versions install as updates.

iOS: no download. Installing on an iPhone requires Apple signing, and the build checked in Apple’s simulator cannot run on a device (why).

About the game

Grumbold the Cinder Mole King has stolen the Sunstone. Pip, a round sprout spirit, runs from the sunny meadow through crystal caves and cloud heights to the ember castle to bring it home.

Meadow Run is fully procedural: sprites, tiles, sound effects and music are all generated at startup, so the game ships no asset files.

No third-party assets: everything is generated in code. · How a game is built

Controls

Action	Keys
Walk	Arrows / A D
Jump (hold to jump higher)	Z, Space, J
Run / throw ember seeds	X, C, K, L, Left Shift
Drop through a plank	Down + Jump
Pause	Esc, P
Menus	Arrows, Z/Enter to confirm, X to go back

In the browser, Alt+Enter or the Fullscreen button toggles fullscreen. A gamepad was validated by hand in a Chromium-based browser with one controller; other controllers are untested.
