A great attempt as a Bleach 2D platformer...
There is lotsa replay value in this game, you get to use tonnes of characters as much as you get to search for the whole cast. (Vizards and Espadas included)
The best thing about this game is most probably the fact that it's not a fighting game, it's refreshing this way.
Besides the many characters you can use, you can also watch special cut scenes exclusive to this game.
There are several funny cutscenes that you won't get to see in the other Bleach games and the Animation itself. These would be nice side stories from the intense, main storyline.
The inventory system is a good thing too, especially the way you get to upgrade your equipment at Mayuri's laboratory, buy stuff at Urahara's shop and the best is that you get to assign support characters in a web system.
A bonus feature in this game would be the alarm system. In this alarm feature, you get to assign a character as your alarm tone, which means a character of your choice will wake you up as you like.
On a side note, dump the DS version (dark souls), try this out, it's a better 2D rendition. For fighting, pick the 3D ones on the PSP. For the DS, just stick to Jump ultimate stars.
