You could do part puzzle game, part rts. What I mean by rts is that you can give the knight commands but you can't control him directly. And maybe he doesn't always do what he's told, and you have to account for that somehow?
Could make for an interesting roguelike, too, as you try to help this endless stream of knights rescue you.
Play video games. Bake bread. Learn to code. Create music. Maybe create a game of my own some day. Release it 100% for free because all my needs are met.

Um? I'm making more than twice that and I can just barely afford rent, food, etc. I'd hesitate to call anything below $15/hr even remotely livable, and that's out in the sticks.
Bad. Do not recommend.
