Glad you liked my additions.
for the sounds I mostly downloaded cc0 samples from soundly and freesound.org and modified them in audacity.
I did record some myself too for example the ambient sound is a forest sound layered with a pitched up version of my laptop fan and some white noise :p
all in all, I hope more people will at least find out about this jam. I think it was a sweet community achievement that a lot of participants would like to know about
