So a new update recently released that while not nececarily making this guide obselete, it did change the balance of how to play the melee weapons so heres a quick rundown:

Melee weapons are now so plentifull that you should always start throwing them when you are up against any enemy that cant be dealt with enviromentals.

A good thing to note is that ranged-melee (upside down pistol blah blah theres no correct name lol) deal significantly less throwing damage than normal which means that you unlike the normal melee weapons have to aim at the head to deal critical damage.

TL;DR
No biggie and this guide is still relevant

Enemies and weak points
I will be covering blanket enemy types to keep it short

• Shooty enemies
  Take cover and avoid open sightlines where you have to rely on dodging and parrying bullets.
  
  
• Crows and Spiders
  Keep melee weapons on hand for crows and spiders since they are hard requirements for when they are airborne since crows can only be beaten into submission and spiders need a long range lobotomy in form of a throw.
  
  
• Mr Baton and Mr chainsaw
  Try and throw since both pretty much are immune to direct melee damage.
  B. should be a priority for enviromental damage since its the most effective way to dispose of him.
  C. NEEDS to have ♥♥♥♥ thrown to him since he cant be kicked into enviromentals
  
  
• Barrel Goblins
  Run up to them and back to bait an explosion since kicking them sets them off immediately.
  
  
• Ghosts and Vending machine
  Kick them since they die in one shot which means you dont waste valueable durability on weapons.

Enviromentals

CRUEL features many different enviromental hazards for both you and enemies that can be used
to your advantage, here's a list of them and how to best utilize / deal with them:

• Windows // windows are the bread to your buttery kick and should be used as often as possible for the enemies that are kickable to send them down a wide range of floors. pretty self explanatory
  
  
• Claymores // Kick enemies into them if you have the chance or bait enemies into walking into them. (note that the ghost enemies dont trigger claymores)
  
  
• Electricity // same as claymores
  
  
• Proximity Mines // these cant actually be triggered by enemies which makes them a pain to avoid.
  What ive found works best is sliding past the mine and any enemies next to it which will result in minimal damage aswell as any bystanding boogers exploding with it.
  
  
• Toilets! // toilets are a blessing in disguise sporting thier WC mark and blue color.
  Theres a hidden feature of the toilets that works so that if an enemy is kicked into it, they promptly break thier neck and die! Usefull and comedic!
  simply anticipate the enemy exiting made easy by the flushing sound cue and kick them right back!
  
  
• Enemies // yes thats right, enemies themselves act as an enviromentals if you kick them onto eachother for a bowling like effect where they knock eachother down temporarily so that you may decide further on how to deal with the situation.

Misc-info

Bullet parries consume durability, so try to avoid situations where you'd need to parry. But a slight weapon durability point is worth less than thier respective HP counterpart.

-more studies needed :P
