This is a good example of an autoscroller level. The level felt cohesive and had a good variety in the layout and terrain. The level was challenging without being overwhelming. I think it may have benefited from one extra checkpoint earlier on, since I nearly gave up at one point. I really appreciated the hidden area with the jems.
Something else that was interesting for an autoscroller is having different speeds for different parts. It might have been nice if the scrolling was player activated, so people could get their bearings a bit. Good level overall.
