I lost a few, some were because was winning by such a margin that I was like "imma kill him in this funny way" just to get combo'd and killed. (I'll remember that forever pichu). Others were on stages that made it a bit difficult for me (lucas). In that case I couldn't land a proper kill hit on him because of where he was most game and the one time I ended up above I got up smashed. But the CPU's in this game are much more difficult so losing doesn't surprise me at all. The further along I got in unlocking the harder the matches became.
