Inappropriate and insensitive
What happened in the Philippines wasn't a joke. It's not a situation that can just be turned into a game. I am a Filipino and seeing this game posted up not long after the whole incident is very, VERY insulting to all Filipinos and Chinese citizens everywhere.
I'm sure nobody wanted this situation to happen. Who would have expected it anyway, right? You may have found it funny to make a game out of it but let me ask you this: Are hostages and murders funny and something to be made fun of? Do those things make you happy, more so other people?
Be sensitive to what other may think about this game. Don't add more fuel to the fire. It's already a troublesome case and yet you put this up. That is very insensitive of you.
I suggest that you take down this inappropriate and insensitive game that you made. It may seem funny to you but it's not something to be laughed about. This is a serious matter - a crisis that the Philippines is facing as of the moment and I believe - I'm sure that others will agree with me - that this isn't a game to play.
