The Words We Never Said

Easy game

Maybe I was easy?
A simple heart in a big game
The levels to get there wasn't very hard
A couple magic words was all that was needed for a key
Bad days created loving knights
A princess in a small castle
The dragons weren't large
And the bridge was left open
It wasn't an issue to play with my heart
You had no problem getting in
But letting you out
That's the hardest game of them all
