I'm guessing more people have played the Crash Bandicoot series, so I can compare it to that. It's that kind of platforming game but is a bit easier than any Crash game and from memory doesn't have the time trials and extra gems to collect like Crash. But gameplay wise it's very playable, fun to replay and has a good difficulty level - some challenging levels but overall a game you can complete without a huge amount of frustration. The N64 version is slightly better than the PS1 version.
