I recall Flash Cannon being pretty impressive - it's not got the visceral feel of Retaliate with the scene change, but the fact the majority of it is achieved just with lighting tickles me aesthetically, and the sound effect works well.
Dig is disappointing - it's basically the same as it was in Stadium, and it was fairly underwhelming there. Just statically sinking into a hole and then some lumps appearing on the floor. Boring.
