I think that the name is too generic and popular. You see "murder", the word, in most news outlets, vast majority of movies/games/etc. - any media.

Sure, you have "Unity", "Unreal", "Godot", ".NET" and etc. but I would argue that they are distinct and unique because they have some heavy-weight organizations and popularity behind them. I also think that they are not on the same level of generic use as "murder".

This engine's name, however, will have to compete with the generic "murder" that is already used in various different contexts. Surprisingly, you can still find it as top result if you search "murder engine" so they got that going for them.

Still, would of preferred if it was maybe some variation of "murder" word if they want to stick with that.
