game-2048-tui's Issues

random tiles added even when no updates

When it is not possible for some tiles to combine or move, even then a random tile is added. I think original 2048 ignored such inputs.

example:
initially the grid is

0 0 0 0
0 0 0 0
2 0 0 0
4 2 0 0

then if user gives down input, there is no possible combination or movement possible, still a random tile is added when instead the move should be ignored.

A simple fix is to check if the res is same as the original grid here, that is, no updates have happened, and then return a bool from the function which is checked by this before doing a random insert.
