There has been several feedback recently of situations where there would be no move available. For instance here, here and here.

Ideally, the generated levels should be solvable without having to rely on luck, so there clearly was something I had not implemented. I've then taken another look at the internal solver, that simulates how a player would uncover or flag tiles. And it wasn't dealing with walls of mines very well. Instead of removing mines in that wall, it would get stuck and revert to removing mines randomly.

This updates fixes that, so now hopefully we should be at a stage where no luck is required to solve any level.

This update fixes the following:

- custom settings like grid size and mines percentage could be set to invalid values when using the input field instead of the slider. The values are now checked to make sure they are within range.

- the tutorial text would hide the top bar where the number of remaining mines was displayed. This wasn't great when that tutorial would tell you to check this number. So now the text is lowered just under the text.
