Treasure Adventure World is a more polished sequel/update to Treasure Adventure Game, which has
its own thread from several years back on this very board.
It is possible to wishlist it on Steam or pre-order on GOG already, but its announced release date is Feb 7th. Reviews, Let's Plays and streams should come out around then too. There is also a web page for the game.

UPDATE: The game is out early on GOG. Thanks to mauvebutterfly for the heads up!
Quite many people liked the original game, which you can still get completely free from GOG or
other places (for Windows). I believe the new game deserves a thread of its own too.
