The various ways you can move across the map and clear obstacles are acquired as you play the game and they allow you to skip certain doors in states where you couldn't get through. This door with a 20 on it will be turned into transparent blocks in State-1 and if you have the Ghosting ability, you'll be able to pass through it. Double jumps and C6 explosives work as well. These abilities will have some other properties that aren't related to movement in the map such as being able to dodge enemy attacks and stun them/remove their armor. There is also the B&R engine, but that's much more of an endgame thing!
Currently working on: Continuing the story
Time spent on the project so far: 293 hours
