My Highest Score: 60
So first of all, nicely done, and the concept was quite unusual.
However, I found that the hit sound effects were a bit inconsistent, with it occasionally giving the "crown destroy vaccine" sfx instead of the "vaccine hit me" sfx.
Also, one big problem I see in games like these are that the controls are inconsistent. What I mean is that in the menu, you have to use your mouse, while in the actual game you never use it and have to use your arrow keys. I would have liked it if you had had the option of using arrow keys in the menu, or then letting you move the crown around pointing towards the mouse
