It looks like 3 different artists. One for the sprite, one for the background/gritty scenery stuff, and one for the full spread CGs for H scenes. The background artist is so fucking amazing that the other art styles kind of seems out of place lol.
The writing could definitely use some more proofreading. A proper editor would be even better. The English is on the better side for a non-native speaker (I assume), but it definitely has it's problems. Grammatical errors and typos aside, there is a certain disconnect in the writing style and tone with the amazingly bleak world you've managed to create. One specific problem was the 4th wall breaks by the MC to tell us about patreon or game features or just him talking to himself out loud. I feel like the narrator should be saying these things.
The world building is definitely the strong point, and the background/cityscape art really brings it to life. I was actually hooked during the intro section going over the history and setting. Great job on that!
Hey, man thanks for the comment! You really seemed to have played our game troughfully! That's awesome really. Regarding the art, you are right there are 2 different people working on it! In some of the backgrounds, we had to use creativity to make everything "fit". See some of these as placeholders for now.
About the dialogues and all the text in general, none of us are native or even advanced in English. However, we already found a person to proofread! Actually, he found us(very nice of him) so this will have a great development from now on. The thing about breaking the 4th wall was a flunked attempt to be funny I guess lol. Humor does changes depending on which part of the world you reside in, I guess we have to take this into consideration.
All in all, thank you for taking the time to review our game! It seemed you really played and in general enjoyed what we're doing so far! This project is going to take months or even years to come to an end, in the meantime, all comments and suggestions are more than welcome, so we can keep improving and placing the quality bar higher each time!
