Hey! Artist here. Thank you very much for your feedback. Both the meter and the face expression were to show suspiciousness of a "player". First one was simply to show, how "hot" or "cold" your situation was, and the second one is more of a comic addition. We thought the face expression would be considered more funny for actual players, rather than watching some line lengthen/shorten.
Also the animation part is a mistake on my site, because I am probably a newbie artist, if not less, and secondly I was too excited drawing different sprites to the point I drew 3 sprites of different enemies, but we wouldn't make it in time, if we tried to implement them.
And this is kind of apologetic reply is the only thing I can do to defend our game. Still thanks that you said that our game is nice, we tried.
