The AI is impossible to beat without a lot of experience(If it even is beatable) and the mechanics are extremely punishing to the player only. When it's pvp, it's fair, but only because a person doesn't instantly react to every breath you take and beat you to a pulp by predicting your movements joseph joestar style. "Your next words are..."
Edit: I managed to beat it 8 times. However, learning how to beat the ai was ridiculously hard. It instantly reacts to almost everything you do. The only way I could even do was block round start to get that first perfect block, then keep countering the whole round. This is a good game with an unreasonably good ai, but I wouldn't really call it a fighting game. Sorry.
TLDR Good game, horribly difficult to deal with Ai.
