Ok, this is an amazing game! The animations are well done and fluid. The sound design is pretty good. As Akzidenz said, the rounds are pretty brutal and it feels like the game makes good use of the time constraint. I liked that when you block one attack you receive chip damage. It adds a little to the urgency.
The IA is kinda strange though. In some rounds it just avoids all your attacks and kill you mercilessly; in others you can keep spamming Hook and the IA just keep getting hit. I did it in 3 consecutive rounds :P
