I agree too. People really don't appreciate the work that goes into building a raylib + c++ project. Trust me I am a nerd at this now because I've done raylib for 5 years and can get a project up and running in about half a day. But anyway, yea the non-wasd controls were risky for a game jam because it could be that nobody understands the controls, but I think I got it right after a little bit of tweaking.
