Ok, about Facebook, too bad. Was worth a try.
Regarding the credits, I'm sure of it as they come from the setup program inside the game. I also know that this game isn't listed as an Arjan Brussee game. Still, I'm sure about that one

. Now, Markus Stein making musics ... hum .. rather doubtful. He's far more well known for his (outstanding) coding skill and productions than anything else. Markus name is displayed in various binaries inside the game as the author of SPlay, the replay used by the game.
Anyway, the musics are now online. Search the musics "(2 fast 4 u)" or the composer "Unknown Composers" or simply in today's addition
