The new cover is alright; it's just I don't know if the focus is more on what's going on (the graphical element) or the text/title of the game (the typography). If it's the text/typography, then maybe you should consider increasing the font size to that it's readable on smaller resolutions (as typically the game icon will be seen as just a small square on someone's taskbar).
I'm not gonna bother posting my game (since I don't remember if you played mine or not, all I remember is playing your game and plus, the game isnt a web game), I just thought I'd give my own opinion/feedback on the new cover ;)
