OSX's awk blows up.

src/awk-raycaster - [master] » awk -f awkaster.awk
awk: syntax error at source line 23 source file awkaster.awk
 context is
      >>>  sprite[0][ <<< 0]
awk: illegal statement at source line 24 source file awkaster.awk

You need gawk version >= 4.0.0
Prior versions do not support true arrays of arrays

[Grayson]

Yup.

brew install gawk
gawk -f awkfaster.awk

Then adjusted terminal size to match game window and things worked as expected.

Might make sense to add that to README for osx users.

[Fedor Kalugin]

Done.
