I'm kinda allergic to PC stuff in games so i'll give it 1/5 just in case people think it's a good ideea to make games that ooze ideology. Also the game is bad even without it.
This game has really annoying controls, she's maybe drunk or something so that she can't move in a straight line. Also the board angle is also bad, i can barely notice the corners of the numbers due to the angle. Also if you put a mine correctly you get light balls, so you can just try all spaces till you hit the one that gets you points, no need for thinking. Overall the game is hard only for it's bad mechanics.
Even if the gameplay is good i really couldn't enjoy the game because it takes too much from protal, this makes me compare everything with portal which this game can't stand up to. So as long as you haven't played portal the game should be fine, also you should add a tutorial for every new item added so it doesn't become a puzzle figuring out what you can do with it.
Game was nice but the mouse speed is really slow and anoying if you usually play with one with higher speed, so it would be nice to have an option for sensitivity.
