This game reminds me of the old game 'Abuse' both the extremely clean and functional graphics, but even more the wonderful gameplay. The run & gun feels easy to pick up, 'wasting' or trial-and-error is forgiving and the amount of deaths/respawn is just enough to give to make you feel like you accomplished something even though it is just a simple jump that you mis-timed. Thrice..
Like I said, the graphics are really well done and together with the music give a instant sense of really dystopian environment. This shows that world-building can be easy, without literally saying anything, by having people who understand their arts.
For a game jam game alone that would've been quite the achievement. But no, these guys then go and extend it with the mechanics/concepts that made games like Portal and Pedro go from good to great. Some polish can be added to make the visuals work more into your advantage (this stays, this moves, this was, this will be) with those mechanics. Amazing deliverable for such a short time and shows what a team with dedication can accomplish in a pressure cooker environment.
Whacking you character around and shifting the momentum somewhere else is spot on. Maybe you could add some more Canabalt-style sections to raise the "Weeeeeee" and "F**k Yeah!!.. Look at me" feeling while at the same time (travel) keep the flow high.
Take this game (or it's concept) and built this into something bigger. Shouldn't be to hard for you, if you just commit.
