Parallel Dimension

You had been about to rush upon four most sly "dimension gangsters" in a final, well organized action when they leaded you out of your way with a brilliant trick.

This room is the office of your second selves in the parallel dimension, who are working on the solution of the same problem but they are much far behind you with their results. Though you had already all of data about the four gangsters, a diversion caused by the tachion whirlpool has brought a loss of memory on you. You cannot remember even the gangsters' faces. You have forgotten almost the whole material of investigation you gathered so far.
