There's a demo out for a limited time. The game is worth a look. Here's some copypasta thoughts on my time with the game.

I had a futuristic racing game itch I needed to scratch lately so I went on to the Wii Shop Channel's WiiWare section and downloaded FAST: Raching League by Shin'en. About five hours later, I've unlocked everything there is to unlock and had my eyes bleed from super speed of the last speed class. It's a nice little racer with a color shifting mechanic that can help and hinder you. Races are won and lost over energy pick ups and color pad usage so track memorization is key. The first of three speed classes is easy enough, but the second and third speed classes has your AI opponents rubber band against you like mad. Actually, it might not be rubber banding. It might be a huge difficulty spike between the first and second speed class. I found myself having to perfect my racing in each racing cup in order to succeed. Thankfully, there are only 4 short races in each cup and you only need to place 3rd overall to advance. I'm a bit sad that there isn't much more to the game. I would've loved some more tracks. Still, a nice fun time seeing how there probably won't be a F-Zero Wii.

Some things to add after this was written:
The difficulty/rubber-banding scales with the player vehicle. If you pick the latter and more powerful machines, your two top rivals will sport those powerful machines and some wicked racing skills. Likewise, using the earlier machines will make your time easier. I don't think this scaling is to your favor in the latter speed classes where everyone is much faster.
