Nice to meet you Antonio! I actually watched a video the other day that HeartBeast was in. It was part of a series by Miziziziz called "Four Game Developers, One Art Kit, We Each Make a Game. I wasn't aware of him before that but he does some great work.
I've been learning mostly from Ryan Laley. A lot of the concepts in game dev are so foreign to me that it's taking a long time to even get something very basic working.
One thing I've noticed about the indie dev community is how motivating and encouraging everyone tends to be!
