Pick a clear expression goal
Elvis Funny Face asks players to make a funny version of its Elvis character. The listing does not describe the editing tools, so begin by inspecting what changes are actually available. Choose one expressive goal, such as surprise or an intentionally lopsided grin if the interface supports it. A clear goal makes it easier to judge the effect of an edit than changing every available feature immediately.
Keep a recognizable anchor
Visual exaggeration often reads clearly when one part changes more than the rest. In the game, try leaving some of the displayed face recognizable while altering a single available feature. Compare the result with the original before adding another adjustment. This is an artistic exercise rather than a claim that the game uses draggable points, filters, or any particular deformation system; the tools must establish how the change is performed.
Compare versions by their effect
Mouse and touch are listed as inputs, but there is no promised save, undo, or sharing feature. If the interface allows returning to a previous state, compare two expressions and decide which communicates your intended joke more clearly. Otherwise, make the next change deliberately from the current image. The goal can be a readable playful expression, without inventing a score or treating mockery of a real person as the measure of success.
