I was so impressed by this! I just loved seeing all these unique characters together! I love Base probably the most. I've never seen Neji with Sonic. I've never seen any Naruto characters with Sonic. Hey with "Super Smash Bros." anything's possible nowadays.
The sprite work was great. You get all these great blasts. There's always something going on. The music's great too. It's just a very enjoyable cartoon.
