Better than most "hit an arrow" flash games
Much better, in fact. I really enjoyed a lot of aspects of this, especially the animation of the characters and objects and ledges and so forth. The graphics themselves aren't that fancy, but you use enough shades of grey and occasional colours to make it much more visually interesting than so many black and white stickflashes, for instance...
anywho, I only have two main complaints. At times after a long portion of no interactivity, the arrow will come up all of a sudden and the player will probably tend to not be ready. Since it autoreplays, that's no big deal, but of course if there's so much time before that arrow comes up AGAIN it tends to get a bit too repetitive when repeating that section.
The other problem is spelling. Don't get me wrong, you've spelled things better than many would, but the use of "u" for "you" and "ur" for "your" is REALLY irritating. You might want to change that. Or not, whatever.
(also, the play button at the start isn't truly a button, you have to click the actual outline of the letters, and that tends to annoy people, making a full rectangular or oval button would be much appreciated in comparison). Overall, though, fun game with LOTS of length (and that's something there needs to be more of on NG)!
