Trackballs for MorphOS
======================

Trackballs is a game in the spirit of Marble Madness: steer a marble
through 3D labyrinths floating in the sky, full of ramps, spikes, pipes,
trampolines, moving platforms, switches and enemies, before the time runs
out. It comes with several level sets and a built-in map editor; the levels
are scripted in Scheme (Guile, included).


HOW TO RUN IT
-------------
Double-click the Trackballs icon. Settings, highscores and your own levels
are saved in the ".trackballs" drawer next to the game.


CONTROLS
--------
Mouse           steer the marble (menus too)
Left button     jump
Right button    accelerate (with a nitro bonus)
Cursor keys     steer with the keyboard
Space           jump / continue
Return          accelerate (with a nitro bonus)
Escape          back to the menu / quit
Alt + Return    switch between window and full screen (also Ctrl + F)
Caps Lock       free the mouse pointer

Gamepad: when a gamepad is plugged in at the first start it is enabled
automatically (it can be changed in Settings). Stick or d-pad steers, first
button jumps, second button accelerates.
