At least it's better than it's home console counterpart, right?
As is to be expected, the game follows the plot from the movie, however, as is to be expected, it's a very, very loose retelling of said story, omitting even more plot points than the console counterpart and adding even more minor plots, such as Norman Osborn hiring Kraven the Hunter to take down Spider-man. There're about 11 levels total, and about 8 bosses, and the game should last you a while. for all the wrong reasons.
Stage design was particularly lackluster, stages are very maze-like in nature, which was probably a good idea in order to get the most out of the web-slinger's abilities, but every single mission in the game is time, which is always fun, and too add salt to injury, about 60% of the stages are of the 'Find X amount of Y' variety, which are EVEN more fun. I lost a couple of lives due to the stupid timer and because I couldn't find the 18th friggin' bomb, or maybe because I hadn't found the blue key I needed to open a door, etc. Not only are scavenger hunts on 2-D action games not fun, adding a timer on top of it isn't doing it any favors, just ask Superman 64 or Hidden Invasion about it.
The best thing you can say about Spider-man on the GBA is that it's better than it's console counterpart... but that's not saying much, now is it? For what it's worth, the game basics work well, playing as Spider-man is fun, the moveset was well thought out, which shows on the simpler levels(The ones that don't have you finding a ridiculous amount of bombs!), but sadly means that at its worst it's not much fun to play.
