Very cool theme and great execution! Super satisfying to fling yourself, and the movement of steering an actively-flying object made it both fun and a unique challenge to hit the differently-sized targets. I loved the zoom-in effect when holding down, which made the variable speed interesting; and I like how much depth comes at the simple interchange of speed/held time and the enemy size/flight pattern. If I had one suggestion, it would be some indication of the disease "heatlh" or time-to-death--perhaps changes in sprites or sounds. Overall, nicely done, quite fun!
