Nothing wrong with someone teaching themselves new things as they create their passion project. I'm sure plenty of people following this project would have to disagree with you on both statements, but he's DEFINITELY not wasting his own time. I personally find it really cool that the game has varying mechanics as you play through it. It keeps it fresh and interesting.I dont mind paying but he really should stop wasting his and everyone time with developing news mechanics for the game that are exclusive to a single scene or area and will never be used again.
