While it is kinda neat, the screenshots are misleading and the game just doesn't have enough meat to it.
Ignore the one screenshot that the game has because the actual game only vaguely looks like it. The screenshot implies that you race against 3 other streams when there's only one, and makes the graphics look a bit differren than what they actually are. While the graphics aren't exactly BAD by any means, they don't match what's in the screenshot. They're quite a bit more basic than what's shown. Though the levels are designed fairly well, it won't take you very long to learn the best paths to take at all.
The sound effects themselves are pretty terrible, but the music is actually quite good and very much worth listening to. The gameplay is very simple, try not to hit the walls, get the energy boosts and the speedup arrows and use your boost sparingly. The speedup arrows speed your stream up for about a split second, while the slowdown arrows slow your ship down considerably. And the boost, while it does work well, sucks down your energy like nothing. Just try not to die and outrun the other stream to the finish line. If you do die or lose, just hit start and you restart the track.
5.0 – Not a bad game, but not great either. It only has single player support, no leaderboards of any kind whatsoever and one mode. It's not a bad game for what it has though. For 80 points, if you're into these kinds of games, it's not a bad buy. I went ahead and bought it after playing the trial a few times, and I've made it up to the 6th level so far. I don't know exactly how many there are, but being that you can't save your progress, I don't see there being that many levels. Go get Bitstream instead, it's a bit more expensive at 400 points, but it's a much MUCH better game.
