Hollow Knight

• You can double-tap your map button to open the larger map.

• Listening to sounds can be a big help for finding secrets.

• If you're having trouble with an enemy, try jumping and slashing downward. This also refreshes jump abilities, and is a necessary skill by midgame.

• Don't worry too much about any Geo you lose by dying, you'll have plenty by the end and it's easy enough to grind for it if you really need to.

• You can't miss anything that counts towards 112% completion, but you can miss some enemy journals. If you're anywhere that seems ephemeral, make sure you get all available entries there.

• If you are going for 112%, the most obtuse charm can only be found
  when you have 15 or more Blue Masks
  .

• Experiment with different charms; very few of them are actually bad, some just don't suit certain playstyles. Some interact in interesting ways.

• You will want to use different charms when you're fighting bosses than when you're just exploring.

• The living have dreams too.

• When you collect essence, return to the seer with
  1800 essence
  and after, try dream nailing
  the white body in the abyss palace grounds
  .

• In the map shop, you can get map pins. Use them to mark places you can’t yet access, and it will help you when you've got the ability that lets you access them.

• You will lock yourself out of the first ending when you
  transform the complete two-part charm into something else
  , so if you want to see that ending, make sure to fight the final boss first. (You'll continue from outside the boss room when you reload.)

• Don’t sell all of
  your relics
  , as you don’t lose them when you die, making them a great way to store geo.

• Inside a waterfall in
  spirits glade
  , there is a relic and a small platform at the
  top left
  . Dream nail the statue to access a cool area.

• Saving and quitting to the menu respawns you at your last bench. You can abuse this if you are lost or are about to die.

• Heavy blow and glowing womb actively make it harder for you, so don't equip them unless you want the game to be harder.

• There is a breakable wall in howling cliffs, and you can summon the
  Grimm Troupe
  here.

• You will die to the first boss, the false knight, a lot. It takes some time to complete.

• Later in the game, remember that more than one NPC can
  receive the flower
  .

• Buy maps. Keep exploring where there are dead ends on the map.

• When you have rancid eggs, give them to the person on the far right of Dirtmouth.

• You may have heard of fancy tricks like a shade skip, e-pogo, pog axe, QGA. Don’t attempt these, as they are for very advanced players who have beaten the game. They skip some items, and can make the game way harder.

• Read the lore tablet just before beating the game.

• Tips to get the endings: Keep exploring, and where you get the dream nail, check the map to find where you should go next
  • You need to complete the 2-part charm. Half is somewhere in
    queens gardens
    and the other half is in
    the palace grounds
    .
  • Get ending two, but when
    hornet helps you fight the hollow knight
    then
    what are those dream particles?
    .
  • Explore the royal waterways more, and complete the
    hardest of the pantheons
    .
  • Ending 4, but he who connects the dreams to realities wants
    a flower
    .
  • After getting an ending, you will find a mushroom who talks. Speak to him
    with spore shroom
    until he flies, and you will get a cutscene with the ending you get.
