...To all the beta testers, particularly Chris Hazard and Clemens Saurer for sending me their custom levels, Li Zhentao from some great suggestions made back in Aura's early days, Yuri for some help around the time I ported Aura to Windows, and Konrad Willmert for his valiant (if unsuccessful) attempts to port Aura to Linux.
...To Shawn Hargreaves and the rest of the Allegro community for the rox0ring Allegro library.
...To the people at Xiph.org for making OggVorbis.
...To Chris Craig and GoldWave, Inc. for their self-titled audio tools.
...To Andreas Voss and Per Sigmond for their free midi sequencer, Jazz++.
