Good idea... But...

Reasons for Cons:

Quite frustrating - Well to start, the game is near enough impossible... Half of the time, your character is on one side of the screen when the rocks are on the other, this would be okay if your player moved fast enough to catch them, but usually you miss them by a mile...

Can get a little boring - Now don't get me wrong, this is a good idea for a game, but all you seem to be doing is hitting rocks... Maybe you could make the trolls throw other stuff in for more points... Maybe have a wider range of sound effects too...

The fact that there's no music doesn't really bother me, I see it as a chance to listen to some of my own... but you could add a music option, just to draw people in a little more...



Reasons for Pros:

Nice Idea - I like the idea of this, like I said before... More stuff can be added, but the fact that there's room for improvement only shows potential, which is a good thing, if you work at this a little more you could have an addictive game on your hands...

Good graphics - I really like the graphics, the screenshot alone drew me in, the graphics really don't need to be worked on as much, the simplistic look works fine with this game...



Others:

Story - This is fine, pretty standerd. A game like this really doesn't need a story, it's like having a story for tetris, but to have one is always a bonus...

Interface - The Interface is okay, But a score display wouldn't go a miss...

Overall - This game is a 50 - 50 for me... It's a good idea, just needs some work...
