All right, lots of small updates pushed out. 

Versions v2, v3, and v4 were fixes for a couple urgent things that broke, v5 added an indicator to show you what new parts you've found, and v6 made changes to actually add the parts for the Watcher and Assassin sets to the world drop pool- internal sister part sets as well. Should apply retroactively for anyone who defeated the watcher, too.

Thanks for your patience and continued support of the game- next update will probably not be for a couple of days, so let me know if you find bugs or other issues. Also let me know if you're having fun with it, the positive reinforcement keeps me afloat.
