This game is a LOT of fun!
I just downloaded the demo of this, and purchased after about 10 minutes of playing! This game is very well produced and presented, with cute characters, amusing sound effects - and most of all it is loads of FUN to play! It's very similar to the "I am an airport traffic controller" games popular in Japan, although a little simpler - for example in this game (at least as far as I've played it which is only the first few levels) you don't have to worry about aircraft ground collisions while taxi-ing, although on the other hand this game adds refuelling and repairs to mix it up a little.
Some may say this game is just another "Diner Dash" or "Cake Mania" with a new coat of paint - and maybe it is to some extent, but that's not a bad thing - for me those games are FUN - and this game even more so.
I also think this game would be great for kids too - maybe slightly older kids so they can get the hang of managing all the planes - but what a great tutorial for multitasking it will make!!
