Fragile?

The blade felt a bit awkward in Ryu's hand. The saber wasn't as perfectly balanced as a lot of the swords Ryu had seen, nor was it as long as many of the polearms he had used. But, when it came to using weapons with a single arm, Ryu had more than ample strength to put it into action. 

Unlike with the staff game, Ryu failed this bubble game almost immediately. While one relied on something Ryu was intimately familiar with, this was a different case entirely. The experience made Ryu realize that maybe his control wasn't as great as he thought it was to begin with. 

Of course, control wasn't exactly the problem. Rather, Ryu innately felt that it was the type of control he was executing. Ryu felt that if someone broke down the exact mechanics of how all of this worked, he could likely do it in a single try. However, figuring it all out on your own was a different beast entirely.
