hello, dear participants! first of all, i want to wish all of you good luck on ludum dare 50. i hope that it'll be fun and unique experience for all of us, especially if it's your first ludum dare (like in my case). and let's hope that the theme would be nice and also, i have a question which i haven't found in an old rules: am i allowed to use any tutorials during the development of the game? for example, if i want to create a system, that i don't know how exactly to do, am i allowed to use any existing tutorials or videos (without using of a source code, of course)
