There are dozens... if not hundreds of games saying that they have nothing but a plain box so that it does not lag for the people that just want to chat. I think that's plenty. I looked at your other game Personnel, and it seems like you followed the Shootorial. You did pretty good with it. I hope that you decide to make more games that you can actually play instead of blank screens.
Wow, Bubble Tanks games have been expanding. Just this year there has been "Bubble Tanks Tower Defense", "Bubble Tanks Arenas", and now "Bubble Tanks Tower Defense 1.5". I'm impressed! Even more-so because I've heard tell of the upcoming "Bubble Tanks 3".
(I heard tell of it releasing by the end of the year, but it is just a rumor)
I love this game and I can't wait to see what else HeroInteractive can put out in the series.
Keep it up!
