I played it a bit (reached 26 germs) but know i don't know what to do and the game isn't challenging enough to keep me going through room. The message is looping on "soon enough" so i think i saw all i could.
As feedback:
Enemies are too easy to avoid as soon as you get their behavior
Walking back is too easy (it allow avoiding any room you want)
Your player controller as 3 problems : First, walk speed is way to slow (of course enemies's speed must be changed accordingly).
Second: walking diagonally increases the walk speed.
Third: Lack of inertia (this one is harder to fix than the first 2)
