I was actually talking about some mildly cursed Zofia development facts to a friend, and they thought some of these were funny so asked that I share them publicly.
1. All of the character's fingers are the same length.
In early development, characters were a bit more stylized and clunky looking, leading to bulky hands and feet. Whenever the art style was updated, the character's skeleton and animations got put aside while we focused on other things and was never able to fix it properly.
If you're an animator and you see other issues with the skeleton here, let me assure you the rest of the skeleton is much worse.
2. There is no true multiplayer online co-op limit.
While the store page says 1-4 players (because that's what we've tested), there isn't a hard limit set for co-op online multiplayer. This was originally intended in case there was a 4th or 5th player who wanted to jump in as well, but decided not to put a cap in.
I once had a glimpse of 16 player co-op and it was madness.
3. There was once an option to pick up Otters.
Early prototypes had the otters limited in how far they could jump (as they're tiny), so there was an interactable option for larger players to pick Otters up to make jumps for them. Likewise, an Otter could jump onto another player's shoulders.
Technical issues aside, this got dropped because this meant playing as an Otter could make some sections impassable.
4. [Most] Enemies are set up to be playable
We explored a 'counter-op' mode where some co-op players could play as enemies on player death. While kind of funny, the enemies don't have as much versatility as the player characters (such as the grapplehook, most magic, etc) and usually led to the counter-op players massively trolling the player characters.
5. Zofia isn't actually in the game.
The closest you can get to talking to titular character of Zofia is talking to her statue, which doesn't respond to you.
While Zofia has all of her dialogue in-game (though inaccessible), it became jarring as both Luna and Zofia would interrupt your progress to update you on the story, so we ironically put all of Zofia's story aside.
Anyways I hoped you've enjoyed these!
