We currently have three levels, but we'll have to see if that needs to be cut down to two ... it might be worthwhile to publish two complete levels that look really amazing and give up on the idea of having a third level that emphasizes some different aspects of gameplay. Below is a shot from the tutorial level. As you play, different aspects of the game are unlocked. The tutorial starts with simply driving, giving the player the opportunity to get a feel for the car's handling. Next, track placement is unlocked: the player gets to place four track pieces without worrying about hotzones or crystal collection. Those two aspects unlock in series after that, and then the player must navigate to the end of the level after collecting at least four crystals and placing track in four hotzones.
You can see a little slice of level three below. Level three features a lot more driving "off-road" ... a significant portion of the level takes place off of the tracks. The player isn't required, per se, to take those off-road paths, but it's definitely exciting. The third level also features a lot more of the civilization architecture, which looks pretty good.
Feel free to share your thoughts on some of this new material!
