It's endearing...and about as mediocre as you can get.
You play as Frank, an ant-like Alien who is taken captive aboard a large spaceship. During your short time in capativity (literally about 60 seconds) you befriend The Maw: an endearing purple glob with two rows and sharp teeth that will eat anything smaller than he is. It isn't long before the ship crash-lands on a nearby planet, and the two of you spend the entire game escaping the planet and your captors.
Technically speaking, there isn't much to be said for The Maw because the game is just kind of...there. Whether discussing the graphics, the sound, the controls, the level design, or even the game's 3 - 4 hour length, there's nothing to rave or rant about; even the in-game design choices, such as some puzzle and action sequences, are very light. You certainly won't be beating your head against any walls trying to figure out how to move to the next area, and seeing as it's impossible to die in the game, the worst thing any creature will do to you is knock you on your little, blue alien butt once in awhile. Yes, the game is about as mediocre as you can get.
What all of this mediocrity accomplishes, however, is that it allows the endearing and humorous qualities of the game to stand out, and it's thanks to these qualities that The Maw's gamplay never drops to the level of something you'd wipe off the bottom of your shoe. It's these very moments that suddenly make the game feel like it's worth playing.
That's just it with this one: It is funny and it is cute. There are moments that will make you go "Awww" and there are just as many moments that will leave you giggling like a schoolgirl on crack. It's obvious that all of the development effort went into making sure the player feels some kind of connection with the lead characters, and it accomplishes this task well.
So bearing all this in mind, who is this game best suited for? Children between the ages of 3 - 10, most Casual Gamers, and anyone looking for a diversion from any serious gaming will find what they're looking for in this game. Hardcore Gamers (or anyone looking for an in-depth experience) will hate it, as it's about as shallow as the wading pool in your nearest public park. Whatever your do, don't expect any more from this $10.00 title than a few laughs and some cute moments.
