Love it.
I found many "homebrew" to deal with when something happens.
I.e. when i find a locked door i can try to break it. If i break it i roll for encounters +2 and i lower the relevant dice by one step (e.g. from d12 to d10) to simulate the lack of surprise. I may even pick a lock to look thru the door without opening generating the new room (rolling everything as standard) without actually encounter it, even the plot roll, so i know if it is the case to enter the room or keep delving to find more resources or stuff.
This is a really neat system. The lack somebody see in it is totally legit and allows players to make up homeberw rules. As said maybe i will use this as a base for a project i have in mind that has the same spirit and purpose (singleplayer fast delving system) a bit more story driven with prompts and concepts
