Explore a thriving underwater coral reef in search of treasure, so you can report back to your local Adventurer's Society!
The imagery in this game feels like a summer's day, all bright colours and friendly characters. Some underwater adventures are characterised by peril; Santa Tortosa is punctuated with wonder. The logging was a particular highlight for me, and provided a fun added bit of flavour text.
Verb handling is, as always, a tricky beast. How much is an artefact of Inform 7 is not for me to question! However, item states can be unpredictable, and I found unreasonable resistance with the jar. That said, the puzzles are generally straightforward.
Under the Sea is a short game - I took about 15 mins - but is a prime example of a straightforward, cheerful puzzle game.
