Thx guys. I have already made two practice games.
One is called Kefka and The Power of The Goddess.
In this you are Kefka and you have to collect Goddess Orbs. Bad guy is Gestahl that tries to kill you.
The other is my version of Chocobo Racing.
It has weird racers like Interceptor, the turtle in South Figaro cave, carrier pigeons from Mobliz etc.
I'll post my finished product if its any good. Cheers!
