I think it would be good that we explain step by step so everyone understands how to do it.
It's a very slow process so let's take one step at a time.
1. you have to choose a character that is very important to you, cause you are both gonna spend hours, days, months and maybe years together.
2. download fighter factory and ms paint. these two are the most easy to start. I will show how to use them one by one too.
3. choose if you are gonna do a character with existing sprites or if you are gonna create them.
