to tell you the truth there was did a gameplay impact on changing the slime appearance but due to the time constraint i was not able to add different attacks i spend all my time polishing the basic gameplay loop and yea the game was kinda inspired by an anime called "the time i got reincarnated as a slime " so we were on it u start as a blob and fight different enemies to gain different ability and kill the boss to become finale boss so i think it kinda fits the boss theme at the start ;)
