Fun and lengthy, but quite buggy. Jumping is almost useless seeing as tho you can scale pretty much all the walls just by holding down the direction you want to go.
Nice game, especially if it is your second try. Small advice: think resolution of your game wisely, especially if you plan to post it on the web page. Many Unity beginnners (I don't know why) make the screen too big, although the game would look out nice in 800x600 or even 640x480. Otherwise, good entry.
Will you fix the bugs ?
