this is sad to hear, but i wonder: why not release a version of it for free, so that we can see what this game was about?
i heard about this game from a friend, but i never got to play it, due to it being sold for money only, without a free demo to see if i liked the game or not.
i believe that if you released even a very basic version of it as a free sample or demo, more people would get to explore your game and to see if they like it or not.
i dont think that you should remove your game due to it getting a few bad reviews or some harsh criticism. because when we learn from our mistakes, we become better, and this applies to game development too.
but i wish you the best either way.
