why dont update the game?

what is this I save my game and when I wanna load it everything is gone!!!

any release date. Maybe a rough estimate. i just found this game and was like yes this would be fun to play.

I can't remove empty spools from printers. When I run out of plastic, I need to buy a new printer. Every time I need to switch tools, I need to drop them on the floor, then move them to a table. It would be nice if that was a little easier (maybe an inventory system where one could switch between tools with the scrollwheel or menu, etc.) Some prints require painting to get the full payout, but I can't seem to get the painting to work. I try hovering the print in mid air near the floating text, placing it ...

I am not having any luck getting the screw driver to work any tips?
