Oh, wow. My first review. Better make it count...
Whisper, in the absolute best way possible, feels like she comes from an entirely unique platformer. The Hover, aesthetically, is gorgeously sprited, and VERY useful all at once. The Laser is so fun once you get used to it, and having the Rocket for that added utility makes for some VERY fun boss battles. Having the Cube function disperse special rings is a very nice touch, and the Spike function might be one of my favorite wall-crawls I've ever played with.
I've especially had a lot of fun in Chaos Mode, which put the action-focused moveset to the test in some of the most fun, limit-pushing, and dare I say, chaotic rounds I've ever had in the mode. And that first-person mode for improved aiming? Astounding.
The only criticism I have is the inability to use the laser mid-air. It's versatile, but only on the ground, and that's a bit disappointing. Despite that, however, this is one of my absolute favorite characters to use. I can't wait to try her out even more.
