Ingame controls

Fixed Controls

Key(s)	Purpose
`Enter`	Choose a menu option
`Escape`	Go back to the previous menu
`F9`	View in-game statistics (e.g. FPS)
`P`	Pause the game
`Alt + Enter`	Switch between full-screen and windowed mode
`1-5`	Switch weapon to Blaster, Toaster, Missile, Bouncer or TNT respectively. If the desired weapon is not available, try next.

Configurable Controls

These are configurable via the "setup options" menu. Default settings:

Key(s)	Purpose
`Left arrow` and `Right arrow`	Move left and right
`Space bar`	Jump/Swim upwards
`left Alt`	Shoot
`right Ctrl`	Change weapon

Important

Under Windows the Jump and Shoot keys are moved to the right to avoid opening the window context menu. That means Space bar ⇒ Shoot and right Alt ⇒ Jump/Swim upwards. Other platforms may have other defaults.

Game Controllers

Most game controllers and joysticks that SDL recognizes can be used.
However, not all axes or buttons may be available. Needs manual settings.
