I agree with Kolba_Yada. While it is certainly not a good thing that the expansion pack hasn't been delivered, the developers haven't just ghosted you and left with the money. They responded to your post only to be met with more aggression, and you even edited the original post. It's not a good thing that the update is being delayed, but they provided adequate reasoning for that delay (a whole new game). Obviously, the communication from the developers could use some work, since this wasn't a known fact beforehand, and their tone was a bit aggressive as well. However, as a new team making games, I'm willing to give them the benefit of the doubt. In fact, if we get another game for the price of $4.99, would that not be worth the wait?
