I love the boardgame, but the mobile version has some issues. There are only 5 yellow tiles and 7 pink (boardgame has 9 yellow and 7 pink) making yellow objectives more challenging than pink, but worth fewer points. As others have noted, you can't pause the game and return later and it's very easy to try to move the map and accidentally click on a tile and place something. Also, it can put 2 improvements on a tile which seems to be a bug.
