TL;DR: Well worth playing and clearly a passion project.
The art is pretty decent and consistent in quality. The writing is not extraordinary, but it is compelling and enjoyable to read. It has very few, insignificant typos.
Certain mechanics in the 'dating sim' aspect of the game are not explained (well), but just playing along through the game will serve you well for the most part. Most characters have a trust stat and an affection stat. There are also milestones in your relationship that unlocks certain NSFW content. The progression in some relationships feels quite natural, while others feel more rushed and "let's get lewd" - which by rights could just be a character trait, but I do wish that certain characters had more of a narrative arc before falling victim to the mighty cock of ye olde innkeep.
I do like that certain characters have the possibility of sabotaging your relationship based on your choices at key sections - which the game kindly warns you of and gives you a chance to save before progressing. It'd be really cool to see more 'bad ends' for relationships explored across other characters. Not necessarily strictly bad ends, but temporary setbacks would make the relationships between the characters feel more real and grounded. Rather than MC can do no wrong and will inseminate every available orifice. So @dev, if you have something like that in mind - go for it! You've clearly put a lot of time and effort into crafting these characters. While some of the lore is not very original and the twist of many of them not conforming to their racial stereotype... It is also very evident in the writing and how the characters are portrayed and portray themselves, that a lot of care went into their creation. So please-please-please keep fleshing them out and expand on their narratives.
While on review my comment seems a bit loaded on the negative side, I assure you I loved this game. I'm offering the critique to hopefully give you some perspective from this single player. I can't wait to see what else is in store <3
