One of the reasons i would prefer directions ( painted on walls or just simple road signs ) because that would be easier to implement at current stage of development IMO ( Also that would make sense , that citizens of underrail mark directions with some spray cans etc ) , as the game is almost finished. i Agree that remembering every turn in underrail can be quite complicated , so are directions given from quest givers especially because there are 2 exits from SGS one in the bottom and one in the top and then something like "go east" gives you 3 different places to go ( 2 different ways to the east from lower underrail all of it rock blocked ) i can only imagine it gets worse when you reach core city .
Also now i realize most of my confusion came from TNT charges being gated by the game until you get drill parts , they unblock the railroad and you get tnt charges at the same time and for some reason it feels like you should be going to the bottom to lower underrails not to the top , it just felt that way , also as soon as you exit lower underrail there is a Rock blockade to the east which can be very confusing and feels the right way to go , is the "gating" for TNT charges really a must ? I mean underrail is hard game not like you could venture too far without levels anyway , maybe there could be a possibility for TNT charges blueprint to appear in Junkyard traders inventory randomly like special bullet blueprints , and then they would appear after drill parts in Lucas inventory permanently , also if you went to camp Hathor before the drills you could just tell the guy at SGS that they are having trouble with insects and that is probably why they are not answering all you get for that is 100 exp anyway.
