You play the part of David O' Brian, a trapper in the American South at the end the last century. You were rewarded with a treasure map from a Cheyenne big chief which you believe will lead you to the location of a lost gold mine. You need now to explore the land through the wild forests and mountains, solve mysteries and fight unfriendly Indians and outlawed people ready to steal your precious map. You are armed with a gun, tomahawk and knife and fighting involves holding the fire button down and moving the joystick in order to shoot, hit or stab. Sure, without the fire button pressed you can move in any available direction. Clues and objects found scattered along the way can be picked up and carried (i.e. extra ammo etc). You can also trade various of those objects found in exchange to energy, ammunition and potions. Apart of the 2D style gameplay in the forests, you can simply jump into your canoe (!) and enter a different gameplay style in which you paddle downstream the Colorado river avoiding boulders, logs and unfriendly (again) Indians before pulling in at a new location.
Ok, the control of the character is a bit awkward and frustrating at times which spoils playability especially when defending yourself by using your weapon and trying to avoid hits at the same time. More on that, the gameplay is quite tough since you have only one life so you must be careful not to end up on a gap. Other than that, and because of its nice (I believe story), Colorado is good title to play (if you haven't already back then).
Silmarils showed once more their quality in graphics, as they do in almost all of their games. The ST version features great graphics, with greatly detailed and colorful environments and sprites and look similar to the PC (DOS) version using 16-colored screens in contrast to the Amiga version which offers 32. All three 16bit versions look equally pleasant with some extra graphics detail for the Amiga version. The ST version is identical to the PC (DOS). The sound features sampled FX and other ambient sounds that accompany you throughout your adventure. The intro music is a well composed sampled track, based on flute, but the quality here is low.
