In the earlier versions of the game, when you were in water, you could tap the space bar and you would swim upward, then sink again. Like the title says, it was a lot like Mario. I wanted to know if there's a mod that adds this back into the game, or if it's possible to make one.
In the current game, if you tap the space bar, you go up very slightly. If you hold it, you go up until you reach the surface or you let go. The way this works is different, because pressing the space bar "bounces" the player.
That is because of the gravity. either way, though, we cant alter the function of the keys, only what they are bound to.
