One person has discovered a secret on his own and notified me, but the particular secret was actually replaced with a different one for 1.1!
I did give away one secret in another forum though: If you're having trouble with food and starvation- start a new game and type in the name "Fat Bastard" (no quotes, capitalized as I have it here) and then check your inventory!
If anyone has discovered others let us know! I can tell you that there are quite a few in there
Edit, oh yeah- thanks for your support! Glad that you like the game, it should be even better sometime this weekend *shakes fist at Apple* - hurry up!
