En Garde is a great beat 'em all based around fencing.
The gameplay revolves around a mixture of timing during which you can hit the enemy and rispote to open windows to inflict damage, in addition to that you can use the scenery to disorientate enemies, on this basis of gameplay, the game is very solid and is very exciting to play.
In addition to the gameplay, there's a fairly short story based on clichés from old cloak-and-dagger films, à la Zoro, which is great fun.
The game is as solid visually as it is audibly, the art direction is really good, and the sounds and music are coherent and make for a very successful whole.
Overall, En garde is an excellent game, the only downside being its fairly short lifespan and difficulty. The game becomes fairly easy once you get the hang of it, but a greater variety of enemies would have been interesting.
