AAAAAGH!!!!
I loved this game the first time i saw it. I`m a big fan of metal-slug derivatives, so i like the concept, the design, music and characters are also great.
So, why 1 out of 10 then? I`ts frustraintingly difficult!!!! The regular thugs come out of nowhere randomly, and since there is so little space to play in, you usually end up using your melee attack on them, which takes quite a bit of time (thus makig you waunrable to enemy fire) not to mention that you scarcely get to actualy shoot anything. Moreover, there are several situations in which not loosing a life is almost impossible (like the big bear at the start).
All in all the game is not at all fun to play, and since the content is so great, I wound up playing it over and over, getting more and more frustrated.
A prefect example of how to make brilliant game content, but totally screw up the gameplay.
