Wow please stop with this gatekeeping. Seriously, people "posting their crap" is a great thing about open source. More should be encouraged to do so. If you look at my github profile you'll find the crap I wrote when I was 15 and still learning lua and python. The repos are of course archived and not claiming to be "web scale and enterprise ready", but nobody should shy away from learning in the open.
You know what the worst thing about open source actually is? People who aren't owed anything, demanding to only see high quality code for their free enjoyment.
Seriously, this is a neat clearly proof of concept tool for a video game that is entirely about wasting time.
