This uses no extra commands than the provided materials in Hammer.

Basically you get "pushed" by the cube upwards.

Idling makes you go upwards.

Moving aka walking makes you go downwards and the way you are facing. (well, no always, it just reduces you upwards acceleration, leading often to a negative acceleration).

Crouching makes you kind of standing in the air.

One of the problem is that it's slow to go to two sides of a map.

However it is fast to climb.

Another problem is that you can fall very easily.

Could be a cool game mechanic.
