Insanely bad. The entire fast, fun gameplay has been disregarded by the ads, the microtransactions, the facebooksharingbutton on the bottom where you'd expect the ok-button to be after you create an element. Shame. It has turned from a nice casual game to just another cashgrab.
You could make classes for the weapons which are shown when you scroll over them.. so you would know if a weapon will deal only damage when directly hit etc.
