So I know of The Great Protector. It's on Itch.io and not abandoned (for now). It was updated 26 days ago and yes, you play as a knight. The Wood Hungers is also on Itch.io but it's on hiatus currently. Only the first 2 chapters are available. Lords of Aswick is HG, and you can only play as a male mc. The Great Tournament is also HG. You start as a squire and become a knight later. That's all I can remember. I hope this is enough!
