So, okay, I went to Garry Francis's walkthrough up at CASA/Solutionarchive.com pretty quickly for this one. Which is sad. The graphics are cheery and colorful. But it hits the "you have amnesia and are not sure what you're doing" a bit too heavily--and unintentionally, in the case of some verb-guessing.
Being stuck in the cave isn't so bad. This part is decently well-contained, though why and how the combination to a safe is scattered in parts about the area is a mystery. The puzzles are sensible. You find a key in the safe. You get out and climb a tree and even hunt for food! (This part is random and frustrating and chases people off. The next puzzles seem like arbitrary guesswork, unless i am missing something.)
You then find some treasure, except ... except ...
Well, the ending had me shaking my head a bit, too. I felt heckled. Not that that's a bad thing, and not that it was particularly abusive, but the shift from "what's going on here, anyway?" felt as helter-skelter as the game itself.
Given the chaos that transpired even with a walkthrough, I recommend you have one close by if you take the plunge with this game. There's a certain eagerness to it, to give you some standard adventure-game locations with weird twists, along with some puzzles that should feel good to solve. But they bounce from perhaps too obvious to "whoah, that was weird" too quickly.
However, if you're one of those people who can get into playing every game in a comp once you start, take solace in this game having enough heart that any frustration endured because of these puzzles is not lasting. That's how Adventuron rolls.
