It was fun getting enemies infected and moving around them in tight spaces.
The game is visually attractive and has nice spore particles.
I believe making the movements faster would really improve the pace of the game and also give you the quick thrill of wanting to engage in combat or not. Overall, I see much potential here.
I would try making the movement speed faster first and see how it feels before adding more actions like running.
You could make enemies faster, maybe enemies explode on death and you have to dodge spore particles, maybe you have a spore gun and can harvest ammo from spores and enemies before they explode.... There are a lot of things you can experiment with :).
