Yeah, I understand your point! I used to be like why the hell I would want to watch someone else play a game! Well, there a lot of people that can not afford a good PC to play certain games they love, or afford the game cost itself so they watch others play it, it is more like a TV-Show series and can be fun depending on the creator who is posting! Some others watch it for the sake of seeing how the actuall gameplay is so they can judge it themselves before buying, others watch because of the fun moments someone can have when showcasing a game, like Jacksepticeye when he used to play a lot of unkown indie games...etc! There are a lot of reasons to a person watching "Let's Play" videos! Even Indie Developers watch those so they can take notes to make their games better.
For your own game to be chosen by a creator for example on YouTube can depend a lot on the style and taste those having in common with your game! Some love and only look for Puzzle games, others look for Horror, I have seen some YouTube channels only post weird looking indie games, some pixel-art styles game... you got the point!
I will be glad to take a look at your game, already downloaded it yesterday, I have some work to do first then I will get back to yours!
