I have an issue and I don't know if it's normal. I am trying my hardest to learn GameMaker and I see that I have improved, but I can not finish even a simple game idea for nothing. Every time I try to make one, I come across a key mechanic that prevents me from doing so, and I can't find it on the web. One example is how I tried to make a top down shooter. I have the player, he can shoot and move, I have the enemies who follow the player, but they stack, and I can't find how to make them stay off of each other. Is this normal to always run into these problems and not complete games?
