Guys, the traits aren't random. They depend on the parents traits of course, and also the order you click them, but there's no random element. There are a few surprising combinations, for example SHORT + MEDIUM = LONG, and LONG + MEDIUM = SHORT. Check the instructions, and it will be slightly easier.
For like half the world, X and Z are far away on their keyboard. Terrible choice of controls. I played through the game and now my left hand wants to die.
I ran into a bug: after jumping off the swinging plant, when I moved to the next screen, I accidentally pushed the left button and returned to the last screen. And then I couldnt move but jump. It probably happened because there wasnt enough time for the dialogue to appear.
Loved the game, even though it was way too easy. Also, the AI made many obvious mistakes, it would probably be much more exciting to play against other players.
It's fixed now. Sorry for the problem.
