i like the concept, from the reviews below it looks like you fixed the bug of the page going down. add more objective , achievements, perhaps even some upgrades would be nice and also perhaps a boss, or if you really want it make it into a global event, that would be even better. yeah, make it so as us aliens invade we get to pick which country we would get to attack first, and as we progress the story can evole, and if perhaps you want this project to go further, you can have a ying yang effect in the story where as we invade, the governments are forced to reviel what alien technology they been hiding in order to try and stop us from taking over. it'd be your story so really you can dictate where the plot would go and, also how long you want this project to continue. I have faith in you, and from what i've seen i think you have the talent and the skill to pull it off. use the suggestions i have brought to the table and i'm sure you'll be fine. but just remeber to have fun doing it too.
