Lemme join n on the love 4 this game. It was a blast 2 play bak n the day(& deceptively hard,@ times)& the Composer was very talented who crafted a jazzy or beautiful soundtrack when needed. 1 of the levels-Sonata had a music theme. U had 2 bring a music egg 2 the keeper bird each time. It would cheer him up then u could advance & the level music would even change. Turned out u were adding bits to the happy song til it was completed by levels' end. Game was unique 4 it's time and it was made by the Sonic team which makes sense, given Ristar's appearance. Thx khinsider!
