To be fair, Inti are much more used to 2D work than 3D (the 2D concept art for this game looks fantastic), and from replaying the game and getting a good look at the visuals, I suspect the visuals look the way they do partly due to inexperience, but also due to wanting to keep hardware requirements low - if partly because the Vita and 3DS are both planned to get ports. They clearly want to keep the polycount as low as possible with this game.
There's plenty of room for improvement (it honestly feels like a Gamcube/PS2 game with last-gen shaders), but I'm certainly not gonna say it looks terrible by any means. It's the gameplay that's the standout, it's Mega Man mixed with interesting score attack gameplay, it's decently challenging, but much harder to get a good rank. Can't say I'm not satisfied.
