Once you've completed a level you move to the next, but if you can replay earlier levels if you wish by flicking through Frogger's book in the initial options to an earlier chapter.
Several options add more of an arcade-style challenge.
Two retro games bring back memories of the original Frogger, and there are time challenges based on levels from the game. The higher scores were seriously hard to beat, and really gave me something to aim at. The colourful and attractive, if blocky, graphics aren't the most sophisticated in the world but they are a huge improvement on the original Frogger. The sound effects are amusing, particularly the slurping as you pick up a power-up, but the background music can get seriously repetitive after a short while. Frogger 2 is just the kind of game I like, which means that it could have been a major disappointment - but it wasn't.
