Hi
SnagiGames!
It's always cool to see a new face in game development. I understand that this is a project in early development, and as such it might be unfair to offer my criticisms in the form of a review. Instead I shall write a short post detailing my thoughts about what you have shown so far.
I get the impression that you are an excellent artist who likes to draw erotic images of girls in a fantasy setting, who is looking to showcase your work. However depending on how you approach the matter, a game may or may not be the best medium to do so. It would seem that as of now you're still trying to work out what type of game you're making, and while that is fine, in the long run indecisiveness may reflect poorly on the final product. If you're going for a linear narrative, it would be wise to ask yourself if you have an actual story in mind. Otherwise we're going to end up with a bunch of excellent drawings, but lackluster writing which only loosely strings them together, in which case the player might be better off just looking at a gallery.
Ren'Py seems like a good choice of engine for your project. As always it is good to be mindful of that you don't have to use all the tools in the toolbox. If you've done the basic tutorials that come with the engine you'll have noticed that they nudge you towards playing with simple choice points and dialogue branches. As of now the beginning of your game is filled with choices, but most of them only lead to minor variations in the writing. Being bombarded with meaningless choices adds little to the player experience, and it may be worth considering restricting choices to more impactful situations such as beginning/skipping a new scene. Either that or flesh out the impacts of the choices, e.g. let them have long term effects on the protagonist's character a la GGGB. But that of course requires some planning ahead. While it may seem like a good idea to let the player have a say in Yda's inner monologue, like the detail about how she feels about her stockings, in the end it might just make her character feel fuzzy and inconsistent. Whether you imagine her as a sweet and naive girl or a sex-obsessed slut don't be afraid to write her as such. Perhaps her personality even undergoes changes in that regard as the story proceeds?
Other than that I sort of like the writing here. Grammar and such aside you manage to strike a humorous tone a lot of the time. I look forward to seeing more of Yda in the future.
