The game feels a lot more dynamic with the units moving more and the changes to the unit system! and the speed means that the game requires full attention, and the final level was a fun challenge (harpies rip), the only limit to the session length is the hard 5 day limit.
however, the unit system does bug me in one factor, the units are less than interchangeable as the red units are blankly better, maybe the blue unit could be faster in escorting and moving?
