The last game I played, which was similar to this, was a Tekken game years ago on my Playstation 2. I enjoyed that but it did frustrate me due to the game mechanics of it. This game is no different.
On the whole, it is not a bad game. The combos can be quite daunting for newer players due to how quickly they must be thrown together to make them actually usable during a match. Certain characters also seem to be untouchable, if used correctly, when fighting due to their long range.
This leads me on to the game mechanics. The most effective way of fighting in this game seems to be 'spamming' the same combos over and over, which effectively renders every move other than that one, useless.
The character creation on this game is fantastic though. The possibilities are literally endless and as you gain levels, you unlock even more items to customise your characters. You can have 50 character creations which means that there is enough room for you and a whole posse of friends to each make a character.
Overall, this game is not bad but I am glad that I did not spend 40 quid on it. 12 quid does not seem like a bad deal at all.
