Looks like a cool game idea worth trying.
However I had trouble opening the rar files. Tried both downloads using 3 different programs and all reported errors. Can you maybe upload a zip file, it might be easier to access?
Really? I use winrar and that usually works great. I just uploaded a zip version try that one! Should be named "SpareParts_v1.0 (Windows) [ZIP FILE]" so quite obvious. Tell me if it works. Hope it's worth the effort though, it doesn't have much content and is kinda difficult to understand since it's a very rushed Jam Game.
