The Wii U eShop is host to a broad range of download titles, ranging from multi-platform titles from established publishers to releases from companies that may be unfamiliar to most gamers. GravBlocks+ will likely fall into the latter category, as it's the eShop début of the six-man team of From Nothing Game Studios — also known as FMG.
GravBlocks+ is based on smart device title GravBlocks; it's a match-3 game in which you also have to attempt to switch gravity to maximise combos and avoid environmental dangers. The developer states that this is more than a simple port, too, saying that the Wii U release has "a rebuilt engine, new graphics, a new story mode, extra accomplishments, 50 more puzzle stages, and GamePad-centered gameplay with easy on-the-fly switching between touchscreen and controller input".
Match-3 puzzle games may be everywhere on the 3DS eShop, but they're less prominent on the Wii U, so if this delivers on its potential it could scratch an itch for some players.
You can check out the trailer below — this title is nearing the end of development and is targeting a release this summer.
