Thanks a lot to tried to play to my game ! And yes making a game in 3H  is still a big big challenge to me ! 

Yess very clever idea ! At first each time, the athlet goes up, his position was randomize generated.. but it was a little bit to hard to play. So I change my idea. Thank you to give a try to my game and to give me some precious advices.  

Thanks you !!
The model of the prescribed figure is right behind the player. At first, I wanted to created with shader a transparancy zone represent the shape to respect, so the jumper had to respect it to pass throw it. But not enough time to understand the shader coding so I adapt my idea with the model to respect just sliding behind the sportive... 

Thanks you to give a try to my game and for your very nice comment !!
