General

Field	What it does
Project name	Also the default app name when exporting.
Start scene	The scene the game begins with.
Screen orientation	Landscape (sideways), Portrait (upright) or Any. Play mode and exported games lock to it.
App icon	An image used as the launcher icon of exported APKs. A square image works best.

Field	What it does
Max pixel ratio	How sharp the game is drawn (0.5–3). Lower is faster and blurrier; 1–1.5 is good for cheap phones.
Smooth edges (antialias)	Smoother edges, slower on low-end phones. The editor applies it after reopening the project.
Shadows	Turn all shadows on or off. Off is much faster.
Max particles	The most particles alive at once, all effects together. Keeps cheap phones smooth.

Gravity — X, Y, Z in m/s². Earth is 0, -9.82, 0 (Reset to Earth). Try 0, -4, 0 for a moon, or a sideways gravity for a strange world.

The joystick and on-screen buttons — the same editor as in the Scene tab.
