So either you feel like NTR is important to the story, or you're too lazy to change it to where the game doesn't imply it happens when you skip it. As for the "A good game has NTR antagonists", Lith doesn't have it, yet it's 10x better than this.
You are being a bit rude here. This is my first game. I made a choice and then worked with it. Maybe it might have been better if this was avoidable, albeit that ship has sailed. Most people seem to be fine with it though, from what I can see.
The Elecmon event is mentioned in several dialogue options and I am not confident I can find every time I mention it, without having to read the entire doc to change it either. Lazy? Hardly, considering I will have to think of an alternative idea where you can avoid the scene, while also giving a choice where you cannot avoid it plus said story changes in the text
You think you can do better? Then do it. Either make your own game or wait until the game is finished. I will be releasing the game code then. Not because of your complaint, mind you, but because it was the plan from the start. I want to give people the opportunity to make changes how they see fit or use it as a framework for their own game.
