Earlier this morning, Jared I spent some time with Repulze [$0.99]. It's a sci-fi racing game that tasks you with completing time trials across six different tracks. There's also a polarity mechanic thrown in for good measure. Bash through three red or green barriers in a row, and you'll be awarded with speed boosts, which can improve your times.
We've seen a lot of racers like this -- you know, the hover-y kind of racers packed with outlandish track design and neat sci-fi locales -- but, we're digging Repulze. It has a great sense of speed and the vehicles all have a neat, mostly unique, feel to them. Give it a look if you're interested:
