I've used two different unpacking softwares (Z-Zip File Manager 9.20 and Unzip: Zip & RAR Extractor 1.0.6) and both have errors. I've downloaded the zip file twice and it didn't work either time. Is it just me?
OK, thanks team. The download was weirdly slow both times, I wonder if itch was being weird that day, or possibly my virus blocker was being a jerk about it. I'll retry.
