Okay a quick v6 review: The update is pretty nice, i like how the mal0 customization was properly finished and i like it. i like the new items as they help.
Now for encountered bugs:
-Lube bottle (Empty): i tried to use it on the new trade place but it didnt do anything, tried to interact on karelia, other than being able to do the nsfw scenes the bottle didnt fill out, i dont know if im missing smth?
-Tutorial: it ran pretty well, and works great, but you can bug it out and have karelia not chase you, so you can skip the entire tutorial and get to the exit, witch get's ya softlocked and unable to do anything. i suggest adding a cutscene at the start of the chase instead of having to be close to karelia. and being unable to interact with the hatch even if you get the ladder, also the lighting is a little funky and you can see a white ceeling and karelia is pretty lit up.
-Futanari cosmetic: It works fine, and is a good cosmetic ( i like futa's.) but it doesnt really fit well on the nsfw scenes due to clipping on the player character or karelia.
-Player character in free cam: small change ya can add is adding a blank head, instead of it missing its head. for example in another itch.io game called FoxDenRemake v1.4, they used a blank head for the player character in nsfw scenes instead of it missing the head.
-Machine Missing arrows: The machine you use to open the hatch has missing arrow icons both up and down.
End comment: That should be all for now. im not sure if i missed more but other than that its a great game and i hope to see more, im a simp for karelia and Mal0 anyways uwu, Have a good day and i hope development goes well!! Also its Togen Aproved!!
