Refreshingly addictive!
This game appeals to a retro side of my that doesn't get to come and play so often.
The game mechanics, style, music and upgrade system is all so perfect! Its ONLY downside is that it's a little long to get it going again just to crash and burn at near the same level as you did the last game. Otherwise it's a perfect game.
Almost every aspect compliments each other so well to the point that you'll find that hours have passed before you get bored, and even then you have to come back and play some more!
This game has huge potential and I highly advise expanding it to the extent of making it a Facebook application!
