I NEED MORE ABOUT THE GAME
Excellent job on making Rot With Me!
I know I said it in my comment, but this was definitely an awesome visual novel and I think the finished version will be amazing!
The story behind Fyodor's immortality was very interesting (and I liked the premise a lot, as well as the fact that the immortality technically came with a price. Like being a vampire but worse, except Fyodor liked the killing aspect.)
Your art style is gorgeous and you made both Fyodor's and The Crawling Rot's designs very attractive.
I was also pleased that we could summon The Crawling Rot, and that we had a choice in helping her or not (even if helping it was absolutely my favorite ending.)
Honestly, the endings all had a good array of variations between them!
Your writing overall was very solid! The story was fun and the characters had delightful personalities.
I think the only thing that made the flow of the story a little less smooth was when the perspective changed from "I/Me" to "You" in a few sections (when we introduce ourselves to Fyodor and when he drags us down to the murder room) But it didn't affect the understanding of what was going on.
But I just want to thank you for making this delightfully fun (and gross) story!
I hope that you continue to be inspired to finish it, and I hope you continue to make more visual novels in the future!
