I can teach you why functional programming matters and where to get started. Or how to learn to program in general.
We started gamedev in 2010 with browser based strategy game Nebula 44. Then we did Orborun, a mobile action game, Fun Kid Racing, which had 50M downloads and currently are building Project Zero Deaths.
Not an expert, but I have been investing since 2017. So if you want a primer of what and how, we can talk about it.
