Another mixed but mostly positive review comes to us from Computer Games Online, citing the same limitations. However, in this one the author recognizes that there is at least some capability to alter Oni's interface, even if he feels this should have been an in-game option.

As it swings between being the best combat PC fighting game in existence and a frustratingly limited one, Oni feels somewhat like a sketch for a much bigger, and better, game. It feels a little like the contractual obligation game—the one Bungie had to finish before moving on to bigger and better things like Halo. Somehow all of the missing pieces can't completely dilute the impact of what is a terrific, if somewhat slight, combat experience. It's so close to being a masterpiece that you'll inevitably be disappointed, but when you step back and look at the whole instead of focusing on the parts, the one thing that stands out more than save limitations or the lack of configuration is the spectacular action. And that's ultimately what matters most.

This paragraph sums up the reviewer's feelings, but the article is still worth a look. I've personally found CGO to be my favored online review site since PC Gamer became a part of Daily Radar, OGR became a part of Computer Games Online and Adrenaline Vault started slowing down.
