since u even said it that u just playing a few hours i would rate u just keep playing for 1 or 2 weeks and everything will come from itself.
no one was pro from the beginning, everyone stardet as noob and had to get at the level where he actually is.
also u mean cpu, if u mean the reaplys which are in the downloaded version. these moves aren´t by the computer. they are made by some people out here of the community. so its absolutley possible to do something like this.
i would also rate u to play some rounds in the multiplayer! its alot of fun and u will meet some nice people there.
it also helps u practicing!
if u still got any questions feel free to ask
