Love it, 15 year old me would have loved it.
I think this might be my favorite Star Fox game. The decision to turn the overworld into a strategy lite game works so well and adds an element of randomness that keeps the game fresh. First game I played I died in a dogfight and my partner died in the asteroid field. Next game handily beat it without letting Corneria get hit and Fox had his blaster upgraded. Part of this was my improving, but also part of it was the way the levels were split.
The dogfights are pretty cool and add something that Star Fox 1 really needed, a way to make Androsses guys feel real. The Mirage Dragon is kind of cool, but I hope it is harder in the harder difficulties.
The controls are Star Fox. The Arwings feel heavy, they don't feel like they can turn on a dime. The walking controls are pretty good for not having dual sticks, with L and R rotating and Left and Right strafing. Switching between the two modes is required to get all the medals, but the animation is kind of an eyesore.
Really glad the game got a release.
