I played f5 to defend e4, restrict white's kingside pawns, and at the same time create a shorter path for my king to the center of the board. Is it a bad move?
I sure like the Rc2-idea. It would have kept my rook much more active.
I'm not sure I'd call it 'bad'. But you're protecting e4 and weakening e6, so you've merely exchanged weaknesses, and why? White wasn't yet on the attack. ...f5 can be played later if need be.
But the most important thing is to make sure you keep your activity. Your K did not actually get to the center. Your R was not posted as aggressively as it should have been.
Sure, the K takes longer to get to the center via f8, e7, etc. but it will
eventually get there, especially if black's R is tying down white's pieces to defense.
The last thing I'll note is that by bringing your K in on the K-side, it couldn't get in very far because white's pawns restricted it. On the Q-side, there wouldn't be this problem.
