Music sounds good. Some of the clips were a little boring, but overall good mix of shots.
However, I think the trailer is far too long. Worse, your individual clips tend to last longer than they need to (example - minecraft fight against the apple guy). The fades between the games is a good touch, but the fade takes too long imo.
So, here's what I think - shorten up some of your clips, and cut the fade time in half. It'll make the trailer feel more energetic and interesting overall, and you'll have a better shot of someone watching it the whole way through.
Good luck!
