Sure this score looks strange. Maybe he just waited for the special ship with only 1 invader left at every level...

For the area, I mean especially the down triangle... But maybe it's my fingers too big! Otherwise in the menu, when you click on for exemple 'Hi score', you have to click on the image, but in my opinion if you click on the word it should work as well

edit: what about some extra-lifes every xxx points or xxx level??
