It does look bad, but this is about the core design of the creatures, not the gameplay. I think we should be concerned if this meant making a game clone like how first-person shooters originated as "Doom-clones" was off the table.
That would make games like iphones, only the smallest change allowed between each generation, Atari would rule the game universe, the kids would be playing jumpman in 4k resolution (Now with 256 colors and 12 unique levels!)
