if a grappling hook was used on a door, the door opens just before the player crashes into it, allowing maintained speed.
This could be used to instantly start Hermes boots, gain speed in boss battles (thought most classes will be a bit restricted due to doors stopping projectiles and some minions, while most bosses tend to ignore tiles), and a boost to skybridges and hell bridges.
I can imagine this to be exceptionally good in the wall of flesh battle due to the doors blocking lasers and hungaries.
