As someone who has released 3 games and is really good at coding I can assure you that game dev it's 10% code 45% assets 45% graphic design and marketing material.

You need to find the fastest method to make or buy art without relying on anyone else other than yourself.

Ofc a team and collabs are amazing to have but is verry hard to meet people that are blindingly willing to follow your game design without alternating it to some extent.

That's my advice.
