I've finally got around to picking up this project again. Just a quick update to the HTML5 version of the game. Some commenters had pointed out that you couldn't quickly uncover all hidden tiles around a number if you had the correct amount of flags placed. This appeared to be an issue with GameMaker itself which is now fixed. To do so you hold down right click and press the left mouse button on the tile. This mimics how it was programmed on WIndows 98.

Please let me know if any new bugs have been introduced with the HTML5 export as the GameMaker engine has had quite a lot of updates since I've last worked on this project. I've had a quick look through my old code and have fixed a few errors introduced with the new engine updates but everything should be fine now.

The desktop exports have not been updated as they weren't affected by the above bug. If there are anymore features that you would like me to add or if I come up with any myself I am open to continuing development.
