Sorry folks, but if you need to be explicitly told to install wget, this isn't for you and I'm not providing that level of support. That's a lot of work, and I don't recall ever seeing a README advise me about installing wget, or that I can swap it out for curl with the correct command line flags, or... I'm also not teaching folks how to install git. I know that means this won't be for everyone, but I'm OK with that. Even if you manage to get this working, your problems will only just be getting started, because now you've got to learn to use a full game engine to create games, and that's going to involve lots of research, reasoning, and trial-and-error. I'm not going to rehash this every few dozen posts or so, so consider this my final note on the subject.
As an update, I'm trying to find a binary hosting service that I can automate CI uploads to. I was hoping GitLab releases would work, but apparently that's still in progress. I've dusted off my old Bintray account, but its interface is a bit inaccessible and I'm working on mastering it. Hopefully I can switch to releases for GitLab 12.8 or so.
