Parkour, Canabalt and Death Race..
Ok- let's start with the graphics; nicely detailed and unique- without being distracting, and each one is appropriate to the it's level. Can't fault you there.
Gameplay- The physics could use a few tweaks, and the controls need sharpening (it's like running on ice), but it adds to the challenge, instead of making it unplayable. Oh and the rewind feature is fucking awesome, wasn't expecting it- top notch programming there- makes dying more fun!
The plot is similar to the film 'Death Race' - where you must run/race for your freedom, and you've clearly taken inspiration from Canabalt too- brilliant work.
On the whole this game is highly addictive, and I still can't find the final sign.
(Try playing this with the soundtrack from Canabalt blasting from your speakers- EPIC!!)
