Contra, but for Game Boy, and with quite satisfactory results.

If you have ever played a Contra, you more or less already know what to expect in the game, such as power ups for your weapon and many enemies and obstacles on screen that you will have to dodge as one hit is enough to knock you down, etc. the typical.

The gameplay is impressive, as it keeps the same action of the NES games, albeit with some changes to the movement speed and jump height to suit the GB screen. While yes, it also reuses many elements from Contra and Super C, such as the music and stages, however this is not always the case, plus the level and boss design is completely its own, so it's not a simple adaptation of the NES games. Other aspects that impressed me were things like the game's graphics, which are detailed and unlike other games for the same console, don't really suffer from slowdowns.

Conclusion
A game with a certain degree of difficulty, which will require several attempts to finish it, quite enjoyable on its own merits and a demonstration of the capabilities of the GB.

A good Contra and a good game for the console.
