This is a Picross, also known as the Griddlers type of game. Even though I'm a sucker for any games that brings me the minesweeper vibe, I simply cannot recommend this game, as it is unfinished and is lacking lots of basic features.
On top of that, I couldn't even say if this 'school project' type of a game would be even a little bit more successful as a mobile game as there are just too many little things that throw you off.
Publisher is greedy and lazy if they are selling this incomplete project of theirs. Do NOT buy this.
