The issues you're pointing out in regards to the use of an image miss the point entirely. As the OP pointed out, a game was copied near verbatim, and submitted with efforts to hide the original title. The original was properly attributed, and the attribution was removed. In the case of the free picture of the eye monster... we can debate if pictures should always be credited, but in this case, the attribution was forgotten.
IMO, actively removing the original title and author(s) of an already existing game is much different than neglecting to attribute the artist behind a 32x32 pixel sprite (especially one that has been used in many other games with a similar level of attribution)
