I don't think anybody should feel like this game is ready at this stage, and I don't think you will get it all perfect until the September release!
Push back the release, and work on the game and optimization. the game being not ready at launch will very much discourage people in buying it.

I know people will not like this because they want the game to be there asap.
but I hope some people understand where I'm coming from!
best regards.
