I had hoped that the shortcomings of the UI from the first game would have been resolved this time around. Unfortunately it’s worse. The directional pad is inconsistent and virtually unusable; hit boxes feel like they overlap each other, as you can often tap directly on a direction and it will read for a nearby button instead. Selected and deselected fill and blank buttons are also difficult to discern unless you know which state is supposed to signify selected and deselected. In the first game this was an obvious alpha change, but here they are just colored in two states, neither of which clearly convey “selected” or “deselected.”
If you can get over the game’s unintuitive and shoddy UI, there’s a lot of puzzles to solve, and it will keep you busy for a long time.
