Thought that the text would be a puzzle but wasn't so sure after about 10 minutes.
Each message tells you which direction to move.
Is there more content to telly, btw?
You can gift teddybears to a few people, like Kid A, who has a special training scene variation if you do that. Telly have a lot of fluff and cute scenes, and some holiday stuff if you set your system clock to Halloween or Valentine's. In silly mode, you could also take the abyssal shard to her, but it'd be a spoiler if you hadn't solved the void instructions before.
Ceraph, if you enslave her, can also do Telly stuff.
And where do you find the codex? Is it like a monster compendium?
Camp Actions, or if you have the bookshelf built, it's at the bookshelf inside your cabin.
Like for instance, an imp would throw a succubus milk or incubus draft at you to trigger some level of transformation.
It should be doable on a code level without too much trouble, though no such functionality currently exists. It'd take going to the imp.hx file and adding to their weighted actions or behavior a new move that needs to be written—"[themonster] sneers deviously and throws [theitem] at you!"— and then if it hits, just have it call transformation function.
As far as I know it, it should work, provided the TF item in question doesn't do anything combat-breaking like knocking you out or making you reset your lust by cumming.
It's a messy design and also ignores the fact you typically have to ingest things to be TF'd, not just get soaked, and a lot of TF items are also not liquid. "The bat-girl throws ''pasta'' at you! Oh no! You're transforming!" Neutron dose beondegi that split your atoms on impact. Still, alternative Game Mode options like Regular Training don't have to be totally consistent, so that's not a big deal. More importantly, would all that many people care for it enough to put that work in to make that feature?
The game is open-source, it's linked in my sig; anybody can code that game mode into the game if it's not popular enough for one of the more senior coders to want to do it
