Interesting concept. Your Turn to Die is my favorite game, and I'm a big fan of Danganronpa so in theory I should like this.
In my playthrough, I went through the initial scenes (influence game, eating). Then visited most rooms in the building interacting with stuff on the way. I just read that apparently you can set traps, but I didn't come across that option.
The thing I was most interested in, is the design and the systems. But I feel like I didn't get to see too much. Like, the prisonner's dilemma minigame, the food poisoning mechanics, the fact that you can put or inspect items in other people's rooms, I liked seeing the little tutorials explaining shit. But the systems are only presented, they aren't really used in any meaningul way. They sound interesting in paper, tho, so I'm curious at least.
Game in general feels janky, in performance, general presentation (like, showing all the results of the minigames of all the characters, or the 3D models of the characters), UX (camera controls are a bit strange. also right click both controls the camera AND triggers the pause menu) and other misc stuff (entering any room shows a message that's like 'This person is already dead, so you can go in', or the fact that some doors are really tiny). I feel like you're biting more than you can chew here in terms of scope. It reminds me a bit of Yandere Simulator, but this is even more ambitious. Ain't a crime if it'll be free though.
In regards to writing, I have nothing more to add than what you already know. Might be worth considering to write it in your native language, machine translate it and manually adjust it.
So yeah, I feel like I haven't seen enough about how the mechanics would work to be interested. But it was fun to run around and see what you cooked!
