I filled out the Open Survey, but I has a connection issue when I submitted the form, so I can't tell if my comments were recorded. I saved some of my comments (shown below) in a text editor.
I played a Halfling Rogue (Budding Osirionologist).
----------
My rogue was effective enough in combat. My rogue class features were largely irrelevant: I lost initiative every time, and flanking was only possible at the end of some of the combats; the encounter areas were cramped.
Even though I was a rogue, it felt like my skills were weak. I broke my lockpicks on my first attempt on the first lock; I hadn't realized that I needed to buy replacements, so I couldn't try again. Lock picking DCs seem too high. I rolled high on the Thievery checks and succeeded on those. I didn't try to sneak, because I needed a lantern to see (which should render stealth impossible). I couldn't tell that the statue was of Pharasma, despite being trained in Religion (with a good modifier, since I had Wis 14)!
Non-magical healing doesn't seem viable at the moment. I played Battle Medic roulette, even though I knew that mathematically it was a bad idea; I rolled well and healed myself instead of dropping myself to dying 1 (I needed to roll 17-20 to succeed, and 1-7 to critically fail). I didn't try to heal others with Battle Medic, because that could be considered a hostile act! As previously mentioned, I had 14 Wis, so my character should have been decent at Medicine. First aid seems currently worthless, — the DCs are way too high, making it more likely to harm than help the patient. Also, why do you need a healers kit to even attempt first aid?
A Cleric was essential to being able to complete the adventure without resting.
I don't think we used Exploration Mode.
