Integrating Crawling into Current and Future Abilities

[Technature]

Had this idea the night character rotation was changed, but before crawling was added:

Using the IJKL keys to rotate your character rolls you along the ground depending on which way you rotate, probably one tile for each full IJKL combo. Faster than crawling, but more effort required?

Rolling into someone could bowl them over

Rolling through doors as they close gives you a few more seconds to pass through, at the risk of crushing

Roll to your belly to get an aimed shot with guns. An aimed shot gets a bonus effect depending on the gun. For example, the hunting rifle could Gib the person's head

Roll onto your back and do crunches to improve your body

Dive out of gun fire, or away from explosions to take reduced damage

Hit the same keys  while standing to dodge bring attacked and reduce melee damage

Manual backflips and dives into the pool

Everything about this idea is really fucking stupid.

Code it immediately.
