For me the level design is pretty bland, it is very much a rinse a repeat for each mission clear first sector, then go into the the next and come back. Basically work out how to get past barrier 1 to get to area 2 and kill bad guy over and over again. Once you get the ability to 'Force Pull' enemies on to your blade it becomes extremely tedious to play.. Never had performance issues with the game, well that is until I stopped bothering with it.
