What role does tower defense elf goo goo skin have?

Hello, I would like to ask what effect the tower defense elf goo goo skin has. The goo goo skin of tower defense elves will make the appearance more lovely or unique, and increase the fun and playability of the game. Because "goo goo skin" is a kind of character skin in tower defense elves. Different character skins only have different appearances, which have no direct influence on gameplay and effect. "Tower Defense Wizard" is a tower defense mobile phone game. Character skin is mainly to increase the fun and playability of the game, so that players can get more personalized experiences in the game. "Goo Goo Skin" will make the appearance of the game character more cute or unique, but it will not affect the character's attributes, skills or combat effectiveness.
