I like the atmosphere of the mysterious lab, and all the workspaces have a lot of detail. Tutorialization is mentioned in a few ratings, but you could just make the first levels simpler. If you disabled the test buttons for the first level and just arrange sequences by number, people would be able to figure out how to play a lot quicker. After each level you enable one more of the tests; it would easily give a natural feeling difficulty curve since complexity is a major effect on difficulty. Good game!
