This needs work.
Well.. what you have here isnt a bad game, but not a great one ether. I like to think this is in the early stages of development. The controls were not very good. (Who uses caps lock as a control? Wtf?) Maybe a simple point and click would be nice. With space being the mine setter, wouldent that be so much easier? The gameplay itself wasnt that great ether, sure it had a "high score bored", but that is no where near enough to make for a good game. Or incentive to play the game.
Good.
1. High scores- its cool to be in the top ten of somthing.
Bad
1. Controls- bad controls= bad gameplay= bad score. Not to mention the odd choice of caps lock as a control.
2. Gameplay- very dull and boring almost quit right away when I saw it.
3. Graphics- although they werent super bad they were no where good enough to really make you want to stay and play this game.
Nonetheless you dont have a bad game here, just fix some of the problems and add some enemies or somthing and you will do fine.
