Trail Stash is similar to Andrew's other wordplay games, but it’s written in Twine (Sugarcube specifically) rather than Inform—so it’s not up to the player to think of (in this case) spoonerisms, but rather, to figure out which of the spoonerized objects you acquire will be useful in each of the spoonerized locations. Success unlocks new locations, which yield new objects.
Being familiar with Andrew’s other wordplay games was definitely helpful in catching on to this one; the “use object in place” mechanic isn’t too hard to figure out, but it also is never spelled out, and the need to spoonerize the place names and object names to figure out which object goes with which place isn’t either. Of course it’s a matter of personal preference, but I don’t tend to enjoy when the first part of a puzzle is “figure out the conceit of the puzzle;” I’d rather just be told upfront. Of course, with the choice-based format of this game, it’s entirely possible to solve it by simply collecting all the items and then lawnmowering through them in each location; I tried to avoid doing this and actually think each one through, but I found some to be clued better than others, and I did resort to random guesses a few times.
I enjoyed Trail Stash as another entry in Andrew’s world of wordplay, but I do think it has a rather niche audience and isn’t going to feel particularly accessible to newcomers to Andrew’s work. But if the concept at all appeals to you, I definitely recommend checking it out!
