The game is quite simple: You are running on a railway. Using left-right controls, you can switch the lane, slide using sneak and jump using space. Specific obstacles require exactly one way too dodge. The theming is for the most part well done: A proper screenshot was rendered, an icon created, the game uses models made during the jam, formspecs were styled neatly.
There are some minor frustrations though: Jumping feels quite odd (like velocity is being made positive up to a point, then suddenly flipped to the negatives instead of a simple upward acceleration + gravity). The waiting period of roughly 5s gets frustrating when you want to have anotehr go right now. Collision could have been implemented a bit better by using the new moveresult feature; the way it's currently implemented serverside, it triggers only after the collision happened; in third person view, you are already out of the obstacle, yet the game is over (I could've sworn I didn't collide with that obstacle!).
Conclusion: Even though this is relatively simple and has minor issues, it is still fun to play. Through it's simplicity, it managed to reach the state of completeness the jam was aiming at rather well, other than some competitors.
