Hello everyone, I am a designer with a very low programming experiences. Mostly, when i see a problem about programming I'm watching tutorials from YouTube, looking for the answer at the forums.I've never been joined to the gamejams.Is there a chance about this stuff?

Of course you can. No one can make a game without checking any reference even experienced people. (Except genius)
If you want, I can share some of my tutorials with you. Here is my channel~

For a lot of people Game Jams are a learning experience. Forbidding to watch tutorials would kill the spirit for a lot of peaople.

I've been a professional developer for more than a decade. Reading the documentation, googling stuff and checking tutorials is a big part of where I spend my time, and some days it's the only thing I do. If you're not sure how to do something or what your options are, why not ask someone with experience? That's what tutorials are to me.
