Bg has a fixed gradient from color palette of the presentation image of the game, gray for streets, red for bricks and cyan from sky (for ANSI users, a little tweak between layers bg2-bg4 and wave2-wave4 may be needed).Color coding for meds, weapons/weapon related options, movement and poses (crouch/prone).There is little feedback animation on the med keys.All keys has a subtle gold wave-dark ripple effect to make it prettier, that can be enhanced through the opacity slider of the two bg separators.Lastly can be used as a normal typing keyboard with the simple layout.ANSI users may need to tweak something since is made with an ISO Italian layout.
