a major issue i have with the game is that even though it's called minesweeper, it's incredibly confusing to navigate, you need to solve missions in each one under a certain amount of turns, which for minesweeper IS A BIG issue because you need to think on it, and most importantly of all the fact you HAVE to move in 4 directions and you CANNOT go more then one square at a time which causes the whole thing to become a mess, i couldn't even clear the first mission because it gives NO context as to how to even solve it's puzzle in the time limit or what your even supposed to be doing, that and the fact the special abilities take into account, and the fact YOUR PARTY MEMBERS move all over the place and you'll have to get LUCKY with if their close enough to give you time for the mission
Eight directional movement is possible and there's no big penalties in taking multiple days to complete a mission. It's impossible to do every possible quest in a single playthrough, so play the game at your own pace. There will be unlockable boosters to help you after finishing the game at least once.
