Hello everyone! I'm pleased to report that Platform Builder version 4.0 is out and ready for immediate download! There are quite a few new features on this massive update, including the ability to make your own store, construct houses and other buildings, and more. To see the full list of updates, download Platform Builder and check out the final page of the in-game manual.
I hope you enjoy using this program as much as I did making it!
