Orbital: Every point counts
Orbital is hard. In Pure Mode (the one, true mode) my higest score is only 37 points. I feel like I earned every single one of those points.
Most games give you 100 points for doing X, 200 for doing Y and 400 for doing Z. Pretty soon your score creeps into the thousands or tens of thousands and becomes fairly meaningless.
The great thing about Orbital is that every point counts.
