You had the review removed because you're talking about development time and tried to sway people into lowering their rating.
That is indeed not a review about the game. Reviews are supposed to be about the content in a game, it's story, renders, writing and so on. What you wrote there is criticizing a developer for his processes, assuming the abandonment of the project and, as mentioned, trying to make others lower their rating.
There are no thoughts about the game itself.
Not a big deal. Happened to me before and I received a warning aswell.
