You're going to get an influx of new comments thanks to Markiplier! He's the reason I'm here, too. This game is so delightful, I've lost count of the hours I've spent playing it today.
Others have made suggestions much more substantial and constructive than mine. I have just one request: Can you please give us the option to make that adorable Royal Advisor into our Royal Queen? 馃槏 She has such a cute design, and the kingdom would simply crumble without her assistance. That alone is enough to make any ruler fall in love, I think!
In all seriousness, though, it might be nice to implement some personal development for the king: obtaining a queen, siring a royal family of future heirs, etc. -- Something to consider. This game is wonderful enough as it is in its simplicity.
