When you download the game it also has a ingame manual to how to change the files and which command does what. Read that manua. What i did was i removed all the incoming obstacles and changed them to netural animation. Look i cant properly explain here but if you read the manual x was a natural s was a natural but with animation and p is to speed up and these was a few more commands that i cant remember like d was a obstacle so i removed that d and made it s. If you still didnt understood it i will try to explain further.
