• Genreal Tricks

 Score screen skip :
 Going to the world map and going on the level you are (the next one, 
 the game immediatly moves you to the next level on the map after completing a level

Here is an example of the spikes hitbox

 Spike quirk : 
 On both sides of the spikes you got a teeny tiny pixel to land on
 that will not kill you 

• Ninja Mechanics

 You have augmented mouvement speed

 The ninja has a double jump with your low jump

 You have a walljump, the wall jump doesn't use your double jump

 You slide down walls, that can be avoided by holding down

 You can attack while moving

• Ninja Tricks

exemple of the 3-Blocks jump

EIiitti Jump (AKA 3 Block Jump):
 Low jump, then at the apex of the jump do a walljump, then a double jump 
 when you regain control turn around and double jump

 Momentum Boost :
 After a walljump you just get to a higher speed than the intended

 Dropdown walljump : 
 This trick is quiet difficult to nail, but once you get the timing it gets easy,
 You basically need to walljump as soon as you drop from a block, the best example is at 1-1
