How to customize the game from Tutorial: Winter

I’m trying to change the score we can get in the game, after finishing the game tutorial Winter, I can play the game now but i can’t find anywhere to change the score that I can earn the game. Every time the snowman touch a snow flake i get one point. I’m trying to change the point to say 2 points per touch but I can’t seem to find the code or block anywhere that allow me to change it. It feels like the score or point related code is hardcoded somwhere in the tutorial that I can’t seems to find.
Please help.
