Not sure where to ask this, my German is only as good as Google translate.
I notice I missed the kickstarter (by 2 days!) but in it there was an option that spoke about 150 files, I can see some files available to purchase here but not sure this is including everything? I wondered if there was a late pledge option (I know physical kickstarters sometimes do) or if the complete bundle would be available at some point on the online store?
Besides the first kickstarter with the world builder bundle etc, Jorg Cappel also ran a short Kickstarter for a rivers/lake tile set that i have been printing out. There is supposed to be a next Kickstarter coming in several months this year.
I am not sure of a late pledge option but check on myminifactory for the files: Jörg Cappel @Tabletop-Modellbau - MyMiniFactory
