A cool puzzle concept in which is interesting in its abstractness of the setting, a human who has to face the trials of deadly cubes in a empty void, with the objective of eliminating all the cubes except those that are forbidden. It teaches the art of multitasking active tasks while leaving others on hold passively until they are needed, its strategic but free on the movement, which nearly makes it count as a half platformer. Its fun for a while but the mechanics are static from the start and the only thing that changes in-between stages is the speed, patterns and textures of the cubes.

Playing this solely because of the praised orchestrated soundtrack it leaves a lot to be desired, as the variety of tracks is very slim and is around 5 to 7 pieces that loop for about 2 minutes max, this relates to the lack of variety in the game overall as theres not much motivation to get to the next stages other than getting the ending, there are 8 stages in which only 4 tracks are original and from there on they repeat for the rest in order, but i will say from what there is, its pretty good mostly, and outstanding at the time.

Many people say the music is unfitting for a game like this but i find it the complete opposite, the whole theme of the game revolves around the Intelligent Qube being this colossal challenge created by a superior being to help people overcome their struggles, so as getting the ending it gives this little story of depending on the character it brings them back to the real world and heals them in a sort of way after disappearing during the trial, or as the default ending gives the birth of the universe.
More than a game it feels like a concept that needed an evolution to establish itself as a full game, but since most players overlooked it and the later iterations were near clones, its left as the birth of something that never grew up. If anything needs a modern remake even if small, is this.
