Aliens need to die in top-down perspective this time. It works but it gets really tiresome to repeat the same actions. Go to x, defend x, walk to y, defend y and repeat until exit.
Here I write what I think about the games I have played. The score is shown as a smiley before the title of the game.
Note about Movies: None of the Youtube movies that i link to are made by me and i include them only to give you a chance to see what the game looks like. Only the text and the smiley score act as my review of the game .
