Being one of my early memories with the PSP I was happy to replay this game again and enjoy it !. Yes there are a good amount of issues but lord the gameplay loop is fairly unique and simply very fun to play with each level. My complaints revolve around the lack of stages, enemy types, no bosses and there being only 3 types of missions. Past that this is still very much a fun game to play and one I recommend giving a go if you have a PSP!!! I really wish I was able to play this game online.
