You can easily get Indy from one ledge to another, whether it be jumping or using the whip. And attacking your enemies is a breeze, as you don't have to aim or lock on. Some enemies are your typical human scum, while scorpions and other dangerous animals pop up out of the blue. But there is so much more to this game then simply shooting the bad guys. Collecting items is the main aim of the game, with the many pieces of the Infernal Machine scattered among the levels, as well as a few other little things hiding among the rocks and so forth.
Some items are hard to find, making it impossible to go through the entire game in one shot.
Again, this isn't a bad thing, unless you are impatient. Puzzles are another major area of Indy GBC, and most are actually challenging. At the beginning they are easy to accomplish, but once you make your way further into the game, you will find some puzzles that can become difficult to master. And thanks to the simple control system, moving items here and there is an easy task. To tell you the truth, I couldn't really find much wrong with Indy.
