Need help for mechanics for my game

Hi! I am making a fast paced 2d top down horror game where you are controlling a creature i made up (its like a dog but has a really wierd head, imma try and put some art of ut here). What i need is an idea for a special mechanic that would make my game stand out. I already have a sprint mechanic and i plan on adding a jump and a combo system where if you kill a bunch of enemies in a short time you heal.

Btw i also had another post regarding problems with the animation tree: https://forum.godotengine.org/t/my-animation-tree-keeps-messing-up-the-animations-in-animated-sprite-2d/141236

Any help would be appreciated and no ideas are bad ideas :smiley:

Dog reminded me Resident Evil
Movie science from lab

I think from this I would assume his mutated mouth can have whip as tongue, :tongue: infecting enemies to take their live slower then direct bite .
What does looks like your environment and other assets?

I havent played resident evil but i think the idea is awesome! The world you are playing in is a rotting world, full of fungi and that stuff.
