just talk to him, admit you made a mistake but if he doesn't respond after a third attempt then honestly he is full of it and don't waste your time, but don't be surprised if he remains kinda reserved if he manages to talk to you

I doubt he is playing games unless you played games first... wait did you?
At any rate he probably misunderstood and now because you turned him down he has a bruised ego.
Your best bet is to ask him if he wants to go out. Technical he already asked you out first. but when you got back to him you didn't make any actually suggestions you just hinted. People especially men don't always pick up on hints.
