It's funny, I turned on the game and scrolled down the page while the game was loading, then looked at screenshot for a few minutes, thinking that this was a game, instead of scrolling up and click on game window.

I love your sketch drawing style.
The wind is rustling outside my window, and in the game window too. It's kinda scary.
Try to add a crosshair cursor, I didn't immediately realise what i need to do.
I like interface design and overall game mood.
