Gravity: beneficial force of nature or oppressor of humankind? In the world of Amberial, it is both. In this unique platform game created by OddGoo, you play the part of a bouncing ball free to move about your world wherever you wish... horizontally. Unfortunately, you are not endowed with the ability to jump, so you must rely (primarily) on gravity and inertia to navigate vertically. However, what goes down never comes back up quite as far, and you may find yourself stranded on a low-lying platform with no recourse but to roll away into one of many conveniently placed death-traps.
Navigate your way to the goal to complete a level and unlock the next one. However, don't forget to search around for the golden 'A' first—collecting these on each level will unlock three bonus levels, located on the far right of the level map. To help you along your way are a variety of moving platforms, springs, launchpads, and other instruments of locomotion. However, it seems that for each one of these, there is also an instrument of death—red lava, red spikeys, red lasers, red bubbles... noticing a pattern here? In general it's a good idea to avoid anything red.
Analysis: With its dark levels, its unforgiving enemies and its constraint of being subjected to the whims of gravity, Amberial stylistically resembles Saltacol, a game reviewed here in 2004 (and one well worth playing if you haven't yet). However, for movement mechanism, think more along the lines of Within a Deep Forest. In contrast to these games though, Amberial presents a much less frustrating set of levels to advance through. Each is no more than a few screens large and is completable in a reasonable time, without oodles of restarts.
You'll definitely want the sound on while you play: Amberial contains a number of different soundtracks for different levels, ranging from intense to eerie chill, and all of them are high-quality. The music, along with the graphics, the level design and the moderate difficulty help make Amberial precisely what people are looking for in a casual game.
