A small update for Astrofrog which adds an options menu.

A few people felt that the screenshake was too intense, so i added an option to turn it down (or off).

Also added an option for trajectory guides, to help people who might find the game difficult.

List of new stuff:
-Screenshake options.
-Controller rumble options.
-Volume options
-Trajectory guide options.
-New credits screen which is available in the pause menu.
-Small easter-egg
