Currently i have divided my weekend in to two parts . On Saturday i am doing the experimental stuff (level , device creation) and on sunday i am just advancing in the story and create animations (and maybe clothing items if needed)
So on satirday i was mostly working on the new underground base and on sunday i was adding more to the story.
Furthermore , (as seen above in the gif) i implemented more savegameslots . I was afraid of touching legacy code but it worked out =)
So in the new update you will have about 50 Savegameslots.
