One of the biggest drawbacks of Lost Frontier is the lack of incentive to do side missions. High Impact has built an attractive place with a degree of freedom rare in most platformers. But all you earn for going through the trouble of running timed obstacle courses, finding hidden nooks, or flying off to explore alternate areas are precursor orbs. These sound pretty cool, but all they do is unlock visual tweaks. It's a step up from, say, unlocking concept art. But the irony of Lost Frontier is that there's really not enough incentive to explore it.
