SuperTux | Old level release 

Music?

If you're talking about the level, then there were no secrets, but I came up with the secrets!

​@@mister_tux03I'm just talking about the whole game, I'm too curious about it..I just wanna know the game developer and it's nationality

Me not. But Bill Kendrick was the first to develop this game. But now the main one is Tobias 'Tobby' Markus. Most of the game is made by fans of the game. I took all the information from the game credits. But the tropical world, as I know, will appear in version 0.8.0. But this will probably happen in 2025
