Hey so my game is about ready for playtest and I was thinking about uploading that version now since I'll be busier and might not be able to finish as much as I would like before the deadline. Is it okay to update the game after it's already uploaded or is that against the jam spirit? Regardless, I've had a lot of fun working on my project and learnt a lot by writing this!

Of course it's fine to update! I don't think there are any jams that forbid people to update after submission. To me, one great thing about itch.io is that creators can release a game and keep on refining it over time. I don't really like the term early access, but some people call this model living game. Of course, it is equally valid for you to release something and not do any more about it.

Ok awesome! I've mostly participated in super crunchy jams where you submit and then you don't really continue working on the game afterwards. So I wanted to check before uploading. Thanks for answering!
