when do you do the updates?

I generally update once a week or two. You usually can find more information regarding next date and upcoming content on my patreon.

NVM. Saw that my issues I was having were 0.4.3b . Seems they were fixed in 0.4.4.

Look forward to playing that version

the way you put the date confused me.

Will we be able to keep savefiles?

Will the story be updated? just played version 0.4.4a and noticed the buttons are updated, just too good at the game.

There will be more updates to the main story.  Save games are generally portable between versions but occasionally there may be issues with some changes if they affect how data is stored. Some may just cause minor glitches others might break saves completely.

With the large number of changes since it was created an update to the tutorial was needed. That is the main focus of the next update that Mav is working on though there will be other smaller fixes and updates as well.
