Big fan of the original lonewolf CYOA types of books and have run a 5e game follow similar story to Flight from the Dark.
Character creation was straight forward and easy to follow, we opted for the master level creation rules.
A summary of the skills,traits and disciplines would have been handy a this stage for quickly viewing benefits as well as when we played, I thinking some home made cards with key info would be handy so characters can refer to them during the game.
Just to note - The narrator ran this with zero prep, so we were learning as we played.
A few times we didnt have a skill that was called for during the adventure - I couldn't see anything about using skills untrained so we just used a similar skill, ie tracking and/or hunting. I suppect you could roll against a skill at -2 or roll 2d10 and take the lowest,ala 5e adv/disadv rules.
The combat system was quick, just had to get use to the one combat roll per round, whether the hero attacked or the enemy. Armour felt very powerful as the combat chart skews the damage in favour of the the heroes, not much damaged was handed out by the enemy, I got hit 3 times and all damage was reduced to 1. (Defence was 2). Another character had Defence 4 - but was mainly at range. I've noted the armour being powerful has been mentioned in other posts and there are enemies who may be able to pierce it, but at this stage we didn't feel we were in any danger, even again 5 enemies vs 2 heroes. I guess we are Kia Lords so were not expected to die easily, especially on a intro adventure

The interest for me comes from the narrator and players investing in the Kai lords and Sommerlund - something we didn't get a great deal a chance to do, due to the low prep. The narrator has already had a chance to read up on the rest of the adventure, too bring the Kai lord history more into the game.
Also interested in the extra classes as well as future releases, especially one if it cover the world of Magnamund and advanced adventures.
Otherall it was fun to play and something will play again - just need to get more familiar with the skills/traits and some of the disciplines.
