Caribbean Nightmare
I originally tried the German version of this, then gave up and waited for the English release.
I've played several games by this author. They tend to have gigantic maps with a ton of puzzles and allow play by dropdown menu or by parser entry. They also tend to be a little underhinted and a tad undercoded, but with enough hints to help out.
This game was better than usual. I liked its 4 chapter structure. I did end with only 2600 points instead of the full 3130, so I must have missed something, but I found the storyline more engaging and the puzzles more interesting than before. It just felt like things were mostly thought through well. I did find the pseudo-jungle maze a bit annoying, though each part of it eventually gained another exit, making it easier to distinguish them.
There were a few unfair-feeling puzzles, but many of the puzzles were very fair. Maybe using the flashlight is a bit unfair since there are so many places you can check (and using the rag or even knowing it exists), but for the flashlight there is a bit of a hint for part of it. There's a lot of dialogue in the game, which I think significantly improves it.
The idea is that you have amnesia on an island and have to explore it, finding shipwrecks, a parrot and a monkey, zombies, dancing skeletons, and, of course, treasure. There's a giant plot twist in the middle that changes things significantly.
Overall, I found myself enjoying the game. There is still some strangeness; UNDOing at one point instead reloaded the entire game and then ran through all my previous commands, but left me in a completely different place with a completely different score. Tying the string to a tree and then taking the string made things weird (as I didn't use 'UNTIE'). So it wasn't perfect, but it was fun.
