A good Game
It was a pretty good game from what I played of it. I was in a hurry while playing and didn't get too far ((Level 3)) but it seemed like it was a great game.
The arrows were a little hard to use, of course that could just be me not being good with a mouse XP. I also liked the wall scaling, I thought it was quite a clever idea. However I think when climbing up you should let the player decide if they want to slowly climb up the corner onto the sturdy base, or the jump that you have it doing currently.
Also, you should have a different song for each level, because you know people are gonna be coming telling you that the music was good but gets annoying after a while, that's just a fact.
And to end on a good note, the graphics were fantastic, and you shouldn't change them at all.
