That's sooo addictive! You guys did a really great take on the theme, the art is nice, and the tech tree works perfectly (being able to drag and drop it is a plus). The only thing that I didn't like much is relic physics; it gets out of the masks' drop zone all the time, but I think that's intentional.
I got around 17k masks, and am doing 90+ masks per second. I had to force myself to stop playing .😄
