This has been at that price at TRU for a good while now. I know it was at that price back in February, but I don't know how long it was at that price, though.
I played this a bit over the weekend, grabbed it for $13 from Amazon because it was in 3D. It's decent enough, although I have a soft spot for 3D side scrollers like this, Rocketbirds, Swords & Soldiers, etc. The cutscenes are in 2D though and when ever the camera changes the 3D does this weird shift, the only thing I can liken it to is that goes from what ever separation setting you have it set at down to zero and then back up again. I used to love parallax scrolling on SNES and 2.5D games were definitely a step in the right direction but 3D takes the cake.
I've played it for a bit my self and its a decent side-scrolling platformer. My favorite parts are the flying section and the motorcycle section as they break up the gameplay a bit but in a good way. Its not a bad game but it certainly isn't great. its just decent.
