There is an easter egg potato in the game. Only cunning players will find it.

I don't have a linux or mac machine to compile a linux or OSX build of the game, however the source is included and should build with a standard SDL install.

------- stuff that didn't make it into the readme that you should know-----

If you are inclined, you can make your own levels by adding more .txt files to the levels directory, and then changing the 5 to another number in levels.txt

the level format is pretty simple.

each line starts with a command character

l (lowercase L) for a laser
then the X and Y coordinate from 0 to 4
followed by the direction for the laser.
1 points up, 2 points right, 4 points down, 8 points left, and OR-ing them together will give you combinations. eg, 15 is all four directions

s for a switch
then the X and Y

c is a switch connection
then the switch id (zero-based)
then the laser id (zero-based)
then the direction the laser will change to
same rules as laser direction

the lasers are on a 5x5 grid
the switches are on a 4x4 grid
so 0-4 for laser coordinate, 0-3 for switch coordinates

the way it works, you can edit the level#.txt (where # is the level you are editing)
and if you are playing the level in the game, press R to restart the level, it will re-load the level data, allowing you to interactively build the level and playtest it at the same time.

a switch can have any number of connections too
so a single switch can control any number of lasers

BUGS:
if a laser is set to 0 for it's direction,
the beams are invisible and the player will still die.
