There are some Glitches........Like when you hit Back and start the game the doesnt starts from first and the movement dont work  for some time. You can expect for an update really soon for these pesky glitches and bugs. If you use 1080p Exit button disappears or Invisible. The button is there under the Play! button if you want you can click it and it will work but it is invisible.

The real fun part is when you compete yourself with the Highscore. I can never go higher than 11600. I you went higher than that let me know in the comments.

Controls are easy when you are more familiar to wasd movements instead of arrow keys movement. Use your Mouse to Aim and exterminate those viruses!!!

Have fun Time Killing Viruses!!
