I played your game some time ago and already rated it and commented on my thoughts.
The game was cool and I pretty much liked it and the idea, really.
What I've learned is, as you said, publicity is a huge part of the game even if it's finished already and that most of the people don't care about the other games or rating system.
But the best I learned by far is how other people work, the ideas they have and to see these ideas in other perspectives than mine.
With your game, for example, I'd never thought about a mechanic of trust with NPCs, and it can be applied to a seller on a game what just sells x items if he trusts you, for example.
And that leads me to the previous point. Really people, play other games and try different things. I created a post where people posted games and I'm just playing all of them (in fact, that's how I discovered yours) and it can be a f*****g horror sometimes when you see +130 replies with games, but it's totally worth it.
