Ive been following the progress of this game.
Its coming out great so far! I cant wait to see the finished product! By the way, try this control scheme instead: Z = jump and D jump, A = punch and fire with gun out, X = Change weapon, and the directional keys of course as the moving. It works well.
also, there are some rather hard parts that should be easier such as the blue pad jump over the Dark Eco pit in the ruins. And the collision detection for some of the platforms and pole thingies that jak spins on arent big enough.
If you ever make a 3rd game, keep in mind i would be willing to help! I love the jak and daxter series. (I have gotten something up on newgrounds, but it got blammed. But it was good. they blammed it for points.) You should make jak and daxter games for the PSP!
