One of the first monsters encountered in my game Widow...say hello to mister BONEHEAD, a reanimated tombstone. They aren't particularly smart, and very distraught at the thought of existing. As such, they'll charge at you, crying with arms flailing, until they self-destruct one way or another. Maybe you could find some purpose for their short existence...their heads look sort of like platforms.

Attack sequence was unfortunately 2 frames greater than the idle so I couldn't elegantly combine them into an image fewer than 24 frames...yikes. Instead, have this link.
