Modes are like setting presets, you can set a mode and it'll set a bunch of different settings at once. if you apply multiple modes they will stack and whichever you applied last will take priority. if you want only the settings from a single mode, you should reset before setting the mode.

broken slime

due to a typo, slime blocks had default slipperiness (rather than 0.8) until 0.3.1

the modes that existed before 0.3.1 have been given this "broken slime" and deprecated so that existing uses of these mode ID's aren't changed. the modes above should be used in place of these, they only exist for compatibility.
