Gave it another try. What is this? Why can't i get rid of them and play the game? 
Well, u got a microchip in your brain, tho I seem to have miscalculated the size and it is too high up so you can not close them (there is an upgrade to remove them, its more of a joke)
What resolution are you playing? It might be related to that.
Now that I see you got significantly confused by this, I thought that I probably should let the player know that the microchip does that, no idea how I didnt think about it earlier
EDIT: just pushed a fix for those being unclosable and added a thing to show you that you are getting ads
