Nice game! Visuals are really cool, and the music was well fitting. I think with a bit of polish on the graphics and animations, and some work on level design, the game could be expanded into a full puzzle game!
I'd suggest to make the behavior of patrolling agents more predictable (for example, make them always move left and right or up or down, maybe even make them point in the direction they intend to move for the next turn), and also to speed up the movement animation of the main character.
The theme was also well fitting, with the virus expanding, and the idea of having sort of antibodies as police officers with guns was very clever, good job!
