Lost Lagoon is a puzzle-based adventure game released in 2010 by Intenium. The game costs about 10 USD to buy, but has a free trial you can try before deciding whether to buy or not.
The game itself is part of the "hidden object" subtype of adventure games, in which players mostly have to scour the often hand-drawn backgrounds with their cursor while looking for usable items. In Lost Lagoon, you lost your memories after crashing on an island after a turbulent balloon ride. Your goal is to search the island's coasts and interior areas to recover your memory and discover your true destiny. Investigate different exciting locations such as a sunken ship, an ancient temple and dark and gloomy catacombs, solve all kinds of puzzles and capture pictures of different locations, collect and use different items.
The game is an interesting little adventure-puzzle one, albeit very short, as it can be beaten in about 2-4 hours depending on your play style and speed. The puzzles are mostly easy enough, so it is a good choice to get your feet wet in this kind of game. Graphics are colorful and good-looking, although not the best in the genre.
