DISCLAIMER : I don't fully recommend this game but I rated it up because the pro/con balance stays positive.
I'm going to be direct : if you don't like competitive/versus gameplay, just go away. This game isn't for you. No need to read the rest of the review.
Now, if you're still here, you might be interested.
Let's be honest, this game is HARD AS HELL when you're a beginner. The tutorial doesn't really help, there's no solo/bot play at the moment and the only mode available is 1v1 Versus. There is no matchmaking, you are free to join the server you want. This is how, on my very first game, I fought against the 113th world's best player. No need to say I got REKT.
Despite the density (not easy to understand at first glance and not very intuitive controls) of the game and its little balance problems (just check the forums, but it's nothing that can affect you as a beginner) Blade Symphony remains pleasing.
I'm not the best versus player in the world, on the contrary actually... yet I won my first match after a dozen of fights which is not so bad and quite rewarding.
Nice addition : There's Worshop Content available for this game.
Finally, I'd say this game needs time to add what it lacks of and fix some issues. Just give it time.
I'm not going to rate this game /100 as I'm not a big versus player and I don't think I have enough knowledge of versus games to rate this accurately.
