Edit: Previously, I had listed the composer field as 'Follin Bros / Unknown', because I had thought there were no in-game credits and just took an educated guess. After a couple viewers mentioned that 'GEOFF' appeared in the High Score, I again thought it odd there were seemingly no credits at the end of the game or title menu so decided to double check--

It turns out, if you wait a little over 2 minutes after loading the game, a credits screen will indeed pop up.
