# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20230107 bkw: BUILD=3, fix icon size.
# 20211228 bkw: BUILD=2.
# - convert .mod music to .ogg, since -current's SDL2_mixer (and thus
#   pygame) utterly lack MOD music support.
# - use pygame.SCALED to scale the game to the desktop resolution.
# - new-style icon.
