"The lasting appeal for this game would come from the need to upgrade your ship parts between levels in hope of making an unbeatable ship. This motivation will keep you going for a while, but eventually the bland level design and the annoying controls will have you stopping long before the ultimate ship goal is reached. The game just isn't anything that I haven't seen before, and therefore, it seems like I have played and beaten this one many times over. With more innovative controls and more money/things to buy between levels, I could see GOF being a hit, but right now it is just a bit stale. For $5.99, it's hard to recommend this one, as there are many more enjoyable experiences in the app store."
