My group and I played this section last weekend.
While we knew things were going to take longer due to our I experience with the new system, it took a LOT longer than expected.
Combat was not as smooth as we hoped but it was not awful. Spells seemed weaker overall compared to martials.
The heal spell worked well with the casting options.
Overall the game didn't exccite anyone and we aren't playing PF2 anymore. We are adding a lot of the Pathfinder unchained optional rules such as the three actions. In fact unchained has many of the PF2 ideas a the three action system ready to Port to pf1.
