The original Q.U.B.E.'s narrative can be summed up as basically being stranded on board an alien ship with a crash course set for Earth. It was up to as the player to stop it, by solving the various puzzle challenges of the “Q.U.B.E.” The game itself began as a student project back in 2009, developed from the ground up and released in late 2011.
This original build of the game was just simply a puzzler without much narrative at all. However, during that time, the core development team of students would go on to form their own studio, now known as Toxic Games. In 2014, Toxic Games would follow up with Q.U.B.E: Director’s Cut, which was essentially the same game, just now with voice acting and an actual plot (briefly summarized above).
The game itself was an interesting experience, however it did feel distinctly low-budget. This isn't something I can say about Q.U.B.E. 2. During my short time with a preview build of the sequel, I think it's safe to say, in every aspect -- from production values, to voice acting, to artistic design and mechanics -- Q.U.B.E. 2 is a massive leap forward from its predecessor.
