Little Opening Trap

After 5...e4 better move for white is 6.Ng5 then game can continue with 6...Bxf2+ 7.Kxf2 Ng4+ 8.Ke1! Qxg5 9.Nxe4 and I think white have a very slight edge.
I had a game similar with this motif with colours reversed (I play the accelerated dragon) against susansdad which I won in 21 moves. Post mortem showed that retreating the king to its original square is an improvement over covering the white's queen check with a knight. To see the game click here.
Check out my blog about the Accelerated Dragon.
I looked at my position at move 5, and thought i would try this out since the game was unrated. Can you tell me if it works? I'm not talking about taking the knight, i mean was it a good move for me? because it i think it forces the knight for a retreat back to g1, but my opponent played something different and in the end, ended up losing his knight.
please use the move list, ive done some work on it, analysing further =P
