I have good news and bad news. Let's start with the bad news. I'm really sorry to tell you that I haven't started coding yet because I decided to find/make resources first. So please tell me, if you know someone who has MLP backgrounds and is willing to share them. It would help me a lot! And well... I don't know what the good news were supposed to be... The game will be free of course!!
What ponies do you want to be in the game?
You can list them all, but remember that it will take lot of time, if there are many ponies.
