you get about 10-12 hours of play time on the main game but its still really fun

i've played the original computer version which was a lot harder compared to the handheld version. thats probably because i have more patience to sit with the psp than at the computer playing it. the game starts out easy but gradually gets really hard. there are 50 episodes with 5 levels in each episode.if your to lazy thats 250 levels which is incredibly great, plus all the online levels you can play and/or download. The online is pretty sick because you can play the levels the company has made or share your own. some levels get really challenging, like 3 levels took me between 45-60 min each, i was ready to break my psp because there were either so many enemies or just a really tough layout, and i only didnt beat episodes 41 and 43 because i couldnt figure them out for my life. the only thing i haven't been able to check out yet is the multiplayer because none of my friends have a psp and i didnt look to find out if you could play the multiplayer online. for $20 the game is definatley worth the buy, its very addicting and very challenging.
