Well, I finish this playtrough before game in current version ended, and for one reason - at some point past Rail Crossing, game start to really tired me, becouse there was no map, and TOO much levels with 2 or even 3-4 exits.
If there will be no map in the future, I can guarantee that 95% of players get tired at point of Foundry\Camp Houtorn.
Should it be a pure GUI solution, or be it some kind of device, that player can buy for large amount of charons (it's even better) - it's up to the developer, but we need something like this.
