The walking up the walls thing affects the rest of the game too, a big bug

If the aiming laser that shows up when you hold down E is way too bright, try opening up the Scenegraph and changing the HDR Bloom Multiplier to a lower value around 10.

This mod was originally supposed to have an aimed throwing system, with different weapons having unique effects when thrown.

An update has been released that fixes this feature so that it can be used in vanilla gameplay.
Press and hold "E" to aim, and press "Q" to throw.

Spears, Big Swords, Rapiers and Staffs simply do damage as they would in vanilla (though of course, you do have to aim them).

Knives will now stick to whatever surface they hit and make noise, luring enemies towards them for a time, until it expires and does a small non-damaging explosion.
If the knife sticks into an enemy, then that enemy will be incapacitated, and nearby enemies will be lured to their location.

Short Swords are where the real fun stuff is. When thrown, and if you hit an enemy, you will release a cloud of smoke at your current location and, after a delay, teleport behind the enemy you hit.

(I highly *highly* recommend you re-bind the Sheathe key to something else, like "X" or "G".)
