Ok, using dtruss, I was able to figure out the name of the configuration file loaded by the game. It is located in ~/Documents/BIT.TRIP RUNNER/game.cfg and contains the following:
Fullscreen = yes
Resolution = 1280x720
WindowSize = 1280x720
VSync = yes
EnableVibration = yes
I tried to set the Resolution to the native resolution of my Mac Book Pro 15", 1680x1050, however the display was still garbage (but at a larger resolution so I knew that my modifications were taken into account). I then tried to change Fullscreen to no and the game launched in a windows, but with correct display.
So now, I can play when the file contains:
Fullscreen = no
Resolution = 1280x720
WindowSize = 1280x720
VSync = yes
EnableVibration = yes
Update, after experimenting a little in the option, it appears the game use the format 1680x1050x32 for the 32-bit version of a given resolution, otherwise it try to use a 16-bit version. And it seems that 16-bit resolution are not supported (at least not with version 10.6.8 of Mac OS X).
So the final version of the configuration file allowing me to play in fullscreen mode to this game is:
Fullscreen = yes
Resolution = 1680x1050x32
WindowSize = 1280x720
VSync = yes
EnableVibration = yes
To find the best resolution for your Mac, I'll recommend to follow this procedure:
- Go in System Preferences > Displays and note the resolution used;
- Change the configuration of the game to be in windowed mode;
- Launch the game, go into the options, and change the resolution to the resolution noted, in 32-bit mode, select fullscreen;
- Relaunch the game, it should work, otherwise return to 2. and see if there are other resolution near the one you want.

You can't increase the resolution of the Minecraft world, but you can make sure the interface elements don't scale upward.
As of Minecraft Beta 1.5, you can set the scale of the UI by going into Options → Video settings... and clicking on GUI scale.
If you leave GUI scale set to auto, it'll continue to use the old GUI scaling: if your window exceeds 1280x720, Minecraft scales the interface elements up with the window.
