This was great - ran it as a one-shot/interlude during our regular campaign.
Just enough creepy things to unsettle the characters and players. It did take 4 hour or so 2 sessions to complete. Considering the size of the island, there are lots of things to explore, clues to gather, and interactions as well as some pretty good combats that were a challenge.

These are great! Have used them a couple of times now in a new campgaign I started running recently.

The only improvement I could recommend so far is to add a 20 ft x 20 ft square (I haven't gone through all of the 5e spells yet to check if all others are covered, but the 20x20 is one we ran into quickly, so I made one myself)

This was a good adventure to work on listening skills - trying to keep a list of tasks and the order she wanted to do them in to help the most people. It also highlighted that we needed to discuss with her about what is ok to keep secrets about vs things that should be discussed with an adult. Amazing what a "simple game" can make parents realize :)

Such a great idea for this age group - my daughter (and wife) very much enjoyed that they could colour & decorate their characters. (I'm sure next session the character token will get coloured to match)

6.5 year old has very much enjoyed the game - we've played 2 of the adventures so far - one of which we did one evening while on a family vacation - just had printed the adventure beforehand - handful of 6 sided dice and a very compact game to play whereever the desire (or boredom) may strike.

Simple rules, simple math, the adults have had fun, she has had fun. Works on listening skills, critical thinking, some good math practice for the age group, and at least one of the adventures highlighted a discussion we needed to have on what kinds of things are appropriate for "keeping secrets" vs what should be discussed with an adult.
