TO USE AN ITEM FOR FUEL FOR YOUR TORCH: Press A on Keyboard after selecting it (by mousing over)

The Symbols above the Monsters Heads are what body part of your Knight they are going to target. Use this to decide when you need to heal a particular limb. (if is a Star they are going use a special ability, credit: jakethebeest)

The Knight will always attack AFTER the enemies front rank attacks. Use this to time abilities like double strike.

Rolling the scroll wheel will change your targeted foe. (note if you do this after the first double strike attack but before the second you can hit 2 different targets once instead of one twice)

Left clicking on an item will use it or select it to be used if it requires targeting (aka bandages require you to click the limb you want to restore to use, potions require you to target the limb you want to heal)

The Grey bar next to "Level" in the top right is the experience required to level. The Brown/Orange Bar underneath it is "Bravery" when this bar is filled the next attack will hit all enemies in the front row.

The Day/Night Cycle is in the top left. During the Day the Knight regenerates HP constantly. During the Night, you regenerate mana at a much faster Rate.

The astrolabe doesnt reverse the order of the mana regen ( 8.0/3.5/2.5/1.0/2.0/3.0) it INVERTS where its up to.
Eg: If the cycle is 1.0 it will become 8.0. So use it at the start of the night!
