Okay, so I'll start off with some bugs.
It seems there's a bug when sleeping in the bed in Fox's apartment where your health ends up in the four digits!

Another bug in Fox's apartment is that you can walk through the south wall of the ground floor for about 2 tiles.
Every part of the south wall seems affected by this, but you can only walk 2 tiles deep.
I believe that the silk outfit in the Cosplay store falsely says it's a stick when you pick it up.
Spelling errors:
In Fox's dialogue about the planet, they says 'disaperences' instead of
'disappearances'
They also say 'necatities' instead of 'necessities', but I think this is an intentional mis-saying as a joke? Like it's supposed to sound like 'ne-cat-titties'? I was confused at exactly what "joke" they were supposed to be laughing at. If it actually is a joke, there should probably be some delay to the way she says it, like. 'just the... ne-cat-titties' or something like that. Again, might have just been a mis-spelling I mistook to be a joke.
Speaking of, I would start wrapping dialogue in quotes, just so it's clear what is an action and what is the character speaking. Also, fourth wall/narrator bits should probably be italicized, or perhaps bracketed? I would say that actions currently *like this* should instead be italicized like this but *this* is a valid way of doing it too, so it's entirely up to you and I don't wanna feel like I'm imposing a standard.
During the third "submit" action, it says 'your now touching yourself' when it should be "you're", I also think the line '',your opening touching your junk in front of your enemy.' is weirdly worded. I think ',openly touching your junk right in of your enemy' or ',openly touching yourself right in front of the enemy' sounds better IMO.
During the fourth wall break reference to SC1, it should be '
affiliation' instead of 'afilation'
There seems to be a softlock where if you escape from El Shark's ropes, you can no longer submit when you attempt to challenge her again. Not if it's an intentional softlock or not, though.
Random thoughts:
I think it would be good if there was a natural hint to how to get the key from El Shark inside the game. Perhaps her diary could be expanded a bit, featuring a few more days that the player could read? Some could just be fluff about the character, but a bit where she describes an event and maybe laments that she loves it when people submit to her, but people rarely do it. And another bit where she wishes people were more honest with her? I dunno, it could come off as clunky either way, but I think that's a natural way of doing it. The other idea would be to add text to the damage dialogue stating that the player's [insert weapon here] seems to merely annoy the shark, since you don't have your pistol, you could kind of retroactively excuse this as El Shark's skin seemly not being affected by the current weapons the player has, and since the player only gets his pistol after he 'befriends' El Shark, it wouldn't matter after that, since I don't expect you'll be fighting her again after that. Speaking of, I think the whole setup in the left side of the hideout is a bit... well, wasted, since after the hint/door is found, there's nothing else but a bunch of doors with enemies behind them. Probably something that should be expanded on later? I dunno, I guess it depends on how big the scrapyard is later on
I think the items should probably have some type of simple description/stats listed? Doesn't seem to be the case right now.
Reactions to the player's current clothing from Enemies/NPCs would be cool. Like Fox saying something if the player first encounters them while naked, as well as when they're in their apartment. The new Silk set could do something similar as well.
Also, this is kind of an iffy idea I'm not sure you'd want to do, but for the more foul-mouthed/asshole NPCs and mobs, they could perhaps call the player an insult based off their race. So calling the player a "skinnie" if they're a human, or a 'mutt' if they're a wolf, ect. More or less just a flavour idea to make race selection stand out more.
Anyway, that's all for now! Game is shaping up well.
Edit: Oh, and I noticed that fox's "tail" seems a bit iffy-looking right now, and more like a cape rather than a tail. Not sure if that's a graphical bug or not.
