I certainly want to start by extending my thanks to GoG for the beta testing.
I must say though, that the keyboard control functions are not very responsive; the only exception being movement, which unfortunately is so frantic that many times you come to close to a target or come out of position too easy.
The mapping of various functions is also so scattered across the keyboard that it becomes tedious to try and be either strategic or simply respond appropriately with either melee / ranged weapons.
Hey, I totally aggre with you man, GoG deserve our thanks and congrats with AvP / galaxy beta testing and for their services in general.
The thing is, that kind of loose movement that the game have is of the game itself and I don't think that they will change that.
The spread of the mapping, its a problem of older games as they, like Duke Nukem 3D and they can be remapped, but I think that the gamepad support was added by GoG, so maybe they can end up remapping the keys to a more modern configuration, because I do concur that the old remapping it's kind of obsolete.
