Is there anything more to the web version/taster other than the backstory and walking home in the rain? I can't seem to progress beyond that.
I don't think that's the case due to the mentioned size issues when starting the web version. if money is your issue; you can currently download v0.15 without paying, and if the issue is that there are people who might rummage through your files, you can hide such downloaded files through a maze of maps, edit its properties to 'hidden', and if that's not enough you can also lock the files behind user specific permissions (within the properties tab)
