After completing at least one New Game, you unlock Mew Game. You must select 1 to 8 Meowdifiers to play a Mew Game. After completing a Mew Game or Mew Game +, you gain an Item of the First King Set to grant to one of your game files. Which Item you gain depends on the choosen Meowdifiers.

Furever Alone

If one character dies, you cannot revive the charakter and it is game over. “This is one of the harder meowdifiers i easily conqeured ruffer enemies plus fast forward and then i put on this meowdifier and boom i get destroid this is way harder then no upgrades or nine lives or no leveling or ruffer enemies or purre magic or fast furrwards with the only harder meowdifier being naked paws.honestly this is the centerpiece every other meowdifier needs to hard naked paws is easy when you have two healthbars so you still arnt getting one shot no leveling isnt hard when you have two guys effectivly doubling you stats nine lives isnt hard as the dog makes that effectively 18 lives you get the idea everything revolvs around this

Naked Paws

You cannot equip any Equipment. This is likely the most difficult Meowdifiers, but can be countered by being overleveled (see New Game+) and using fully upgraded Spells.

Nine Lives

You can only "Game Over" nine times or you can no longer play on that mew game run This is another easy Meowdifier. However when combined with fast furrward wich makes things require faster reactions and furrever alone which makes dying twice as likely as you effectivly have half as much hp this can be brutal.This limitation ends after completing the game, so you can still challange more difficult areas afterwards.

No Leveling

You cannot gain experience. This Meowdifier is, again, best solved by being already overleveled.

Ruffer Enemies

Different and other enemies appear, for example instead of Skeleton Mages, Skeleton Kings may appear. This is also not too difficult.

Purre Magic

You cannot attack with your weapons, but your Mana regens automatically and quite fast. This is actually a really easy and fun Meowdifier, you can also equip Weapons like Excalipurr instead of a Magic Weapons to not lose Health or Weapons like Dragonfire and The Hawt Dogfor spells, in this case Flamepurr.

The Gentle Suit, Gentle Monocle and The Architect are also very strong with this Meowdifier and Purre Magic also works great in combination with Naked Paws (if you are overleveled).

No Upgrades

You cannot buy Upgrades for your weapons or spells, but finding Items in chest will still upgrade your Items. This Meowdifier can be a bit tricky for a Mew Game, but is quite easy with a Mew Game+ since you keep all Upgrades. For Naked Paws, you want the spells you use to be fully upgraded.

Fast Furwards

Everything is faster, both you and enemies. Enemies also cast attacks and spells faster. This is a really fun Meowdifier, but can be dangerous if you have only Nine Lives, especially if you are surrounded by multiple enemies and there is so much going on that you lose track of what and when to dodge.
