The portal system is each game randomized? (Good I did not spent the time and effort energy to mark / create my own map -> old games were playable only if you used square paper and pencil - and ducktape to attach more A4 square papers together... new games are somehow more intuitive... I just each time used F5 + F8 to proceed trough the labyrinth...
Anyway, I found a MOD with interactive maps... which are all in russian, so if anyone could translate this mod, we (not so favourite to understand Russian) would surely appreciate it:
