Changelog for Patch 3 (added 09 October 2018):

* General: Consistent jump height and more stable physics at different framerates! This should help clear a lot of the generally buggy issues players have commented on. If the game feels choppy, I still highly recommend lowering resolution and/or playing windowed--the game feels really great when playing at full speed!
* Act 4: able to progress story without officially recruiting characters
* Act 5: optional leaf on map appears to be required to progress story
* Act 6: birds don't always respawn
* Act 6: wind changing directions a bit futzy in one segment
* Act 6: softlock with Audrey during bug sequence
* Act 6: A set of jumps are very high and a bit difficult
* Post-game: Gabe can't be interacted with


Changelog for Patch 4 (added 15 October 2018):

Heh??? We made the tragic mistake of changing physics in our last patch, and boy howdy did that cause some problems! Thankfully you've all been gracious and patient with us as we cleared up the new problems as well as some old ones. Here's newly fixed stuff:

* Act 1: Bard leaps lower out of bed on low framerates
* Act 3: Able to jump over certain room exit
* Act 5: Launch distance from bubbles reduced on low framerates
* Act 5: Infinite hug
* Act 6: Birds don't launch very far
* Act 6: Birds STILL don't always respawn
* Act 6: Partner character's pathing not great on low framerates
* Act 6: Some platforming near the end is a bit high for the bard's jump height on some framerates
* Act 7: Reloading the big confrontation would have some heads swapped
* Post-game: Scene select animated to frames and not deltatime

Some Mac users are still seeing memory-related crashes, which we think is an engine issue, and we're talking to Yoyogames about this. Other than that, we're actually quite close to fixing all known issues on PC, which is a big deal! (Can't wait to inadvertently summon many more with this claim, LOL).

Where do you see GOG has Patch 4? It's not in the Changelog in Galaxy or the web... GOG only has Patch 2 as far as I can see... Steam is up to Patch 7 (and beyond if you include the "language build" that came after Patch 7)... I'm going to see if the dev will respond to my email, if not, probably request a refund from GOG

I actually can't see it anywhere as I don't own the game, I just post changelogs as they become available on GOG following the "what did just update thread".

On Oct 9, 2018, Patch 3 was released here, and on Oct 15 another one labelled Patch 2. I thought something's gone south with the numbering, so I quickly checked, and confirmed that the content of GOG's "Patch 2" is indeed that of "Patch 4", hence used the correct numbering here.

TL;DR - the last patch here, mislabelled as Patch 2 (either by GOG or the dev), is in fact Patch 4.

Of course, this doesn't change the fact that the GOG version is a few patches behind the Steam one.

Thanks for the response and clearing that up... I tried reaching out to the developer, but never got a response... this is par for the course on older games, but this is a new game and really shouldn't be happening where the game's not getting updated... it's too bad

Perhaps ping Judas and/or contact GOG Support? Some times GOG needs a little nudge to get on top of things.
