For ones, that doesn't noticed it themselves - for changing camera options, You need to modify "camera", not "key_camera". 0 is default, 1 is lazy camera, and 2 is static camera (You can still rotate it using screen). I also recommend playing a while with view part - i found those settings best:

view_fov 50
view_dp 125
view_dc 20
view_dz 300

Unfortunately, binding a keyboard key to "key_camera_toogle" doesn't work - it's pity, cause on some higher levels, switching camera mode few times during one level would be *extremely* helpful.

Still, this game is really awesome! With lazy/static camera, it's very playable - need some training (it's fine that it's not too easy), but it's also really rewarding. Controlling with accelerometer seems now very natural - like this game was designed for it.

I also answered myself my question about additional lvl sets for neverputt - we just need to click on another tiny image, during set choosing, lol.

Suggestion for mardy:

Please make "camera 1" as default config setting in next release. This will save frustrating moments for LOT of people. If it's possible, setting camera toogle to one of volume keys (or at least, keyboard) would be also very helpful.
