I finished the main part of Bit Trip ReRunner. It is great. As I said before, it is very similar to the original game.
The biggest change is the levels now have optional checkpoints, which makes the game significantly easier. I had checkpoints turned off except for the boss levels
Like the other Runner games, I find it very satisfying to play, even though it is difficult. There is just something about the pace/rhythm of the platforming that just really works for me.
Difficulty overall is a bit less than the original game, but higher than 2 and 3.
There is a video of the final level here

There is also a online mode for downloading levels people have made with the level creator, but I havent looked at that yet.
