Dual Transform isn't a hard game. I don't think it was meant to be hard. It doesn't take too long to figure out how the game works and from there, it's just a matter of using logic to complete the next puzzle. Once you become immersed in the game, logic is replaced by a kind of instinct where you understand what to do next even before you comprehend why it has to be done. The puzzle system creates an environment that is unlike anything I've seen previously. Your surroundings are ever-changing and you must find a way to manipulate them to get to the next "room".
After playing the game for a few minutes, I felt drawn into its beautiful world. Each "room" represents a physical property and the more time you spend in the environment, the more immersed you become in the sensation of said property. The back-story of the PC is never fully explained, but
I didn’t feel a need for more information. The PC is a researcher, trying to design a three-dimensional, sensory workspace. The story behind the puzzle is intriguing, but simple enough so that the player doesn’t get lost in an overwhelming amount of data.
The "one object only" concept was implemented well and simplified the game at some points, while making it harder at others. The descriptions were well-written and used plenty of sensory information to create a realistic atmosphere. The ending puzzle brought the game to a beautiful, surreal, and somewhat surprising close. Hopefully, the author will follow up with a sequel like the ending implies.
