There is no save, it reset now as I opened it so that should be implemented, rather with "export" and then Prestige. And don't be hard against yourselves with deadlines, it does take somewhat about at least a month, a week is way too shoer to develop a descent game with the most basic functions
The game should save your progress automatically, but it's possible to reset your progress from the Options Menu.
As for the deadline, we're experimenting with a development system that forces us to finish games quickly. Once we've applied it for a while we'll do a devlog/blog post about the specifics and how it went.
