cool
I don't usually watch portal entries that aren't green or better, but I liked your title. ;) I'm glad I did watch it. I really enjoyed the style and the energy throughout the whole flash.
There are a couple things holding this back from being really excellent. The music, while a decent song choice, wasn't synced well to the action. It felt like it was just thrown there into the background. Also I would liked to have seen the whole song animated. It cut out rather suddenly. There are two other (small) things. The cut-to-black was overdone in that one part where it's zooming in on him laying on the ground. I liked it at first but it just happened too many times. And last, his eye looked funny. Eyes are extremely important; they tell a lot about your character and a close up eye shot like you did can draw the viewer in. So just always pay attention to how you draw the eyes (there are lots of tutorials online) and try not to omit them by covering with hair or whatever unless you really need to.
Keep making flash. ^^
