My hand! Why must it shake so?!
These types of games remind me of the science fair projects where you had to keep a pin from touching the conductive sides of the object... I always did enjoy those.
Graphics - They're quite simplistic. Fortunately, this works well in a game such as this, where it might become distracting or difficult to see your mouse cursor otherwise. 7/10
Style - Here's where the game shines. The animation is very smooth, which is vital in a game that requires a steady hand. The "Start" button on each stage ensures that you don't lose a life prematurely between levels. You also include a lot of great obstacle ideas, particularly the moving "T" wall. Quite simply, it's both animated and designed well. 10/10
Sound - The subtle techno-esque beat works well, what with the steady concentration required for a game of this type. I also appreciate you not putting in any sound for when you hit the wall, as that would really have disrupted the flow. 9/10
Violence - Erm... Only if you count flinging your mouse at the monitor I guess. 1/10
Interactivity - The cursor is *very* sensitive, which is both blessing and a curse. Fortunately, the smooth animation and relatively small size of the dot tend towards the former. The aforementioned start button is also a positive factor. It would have been interesting to see some user-triggered obstacles added, like stepping on a switch etc. 9/10
Humor - Only if you watch someone else play this, in which case, 6/10
Bugs - When you finish the game, the "Main Menu" button doesn't work.
Overall, quite a well-designed game. You should definitely consider adding on many more levels. If you do so, consider easing or eliminating the level penalty. Although I liked the added challenge, others might find it difficult... Perhaps a difficulty level option would work. Overall, this game kept me entertained until I won, and I typically don't play flash games very long. Keep it up! 8/10
