When Infernal Hunger comes into play you may sacrifice any number of creatures.
When Infernal Hunger comes into play choose a color of each sacrificed creature then put that many +1/+1 counters on enchanted creature. For each color among creatures sacrificed this way put a +1/+1 counter on enchanted creature.
The problem is, the natural templating for what you've written would have the counters removed at the precise same time that this deals damage. Players would get very confused about whether that means this deals damage equal to its power before or its power after. (By analogy with wither, we can see it would indeed deal the full 5 damage.) It's also rather hard to make the rules remove all the counters whenever any damage would be dealt, while simultaneously starting prevention of up to that many.
(Should the prevention apply just to that moment the damage is dealt, or for the rest of the turn? Say I tap a Prodigal Pyromancer at this when it has 6 counters: all 6 are removed and that damage is prevented. But then if I untap the Pyromancer and shoot at this again, do you want that damage to be prevented too, using up another 1 of the shield? Or should the shield go away after the first damage instance?)
If you want to go with that version, then the templating you want would be something like:
> If damage would be dealt to ~, remove all +1/+1 counters from ~ and prevent up to X of that damage, where X is the number of counters removed this way.
It's pretty unusual and pretty tricky though. It might be simpler to just go with the ability from Protean Hydra:
> If damage would be dealt to ~, prevent that damage and remove that many +1/+1 counters from it.
But what would it do to the 3/3? Deal 5 damage or 1 damage? The wording doesn't actually work either way, because the "Whenever" is trying to prevent the damage after it's already happened, but once I understand what you want I can help you find the wording you want.
I'm hoping to integrate more "mutant creature matters" into the set which would interact with cards like this which would be turning creatures into mutants. I think it's intereting a creature turns into a mutant but then doesn't have to be the one sacrificed so it could actually end up helping a player out if they need one of their creatuers to be considered a mutant for whatever reason.
Can still be tweaked later on, maybe it really is just too much text. Can also always be a good opportunity to divide up a card into two seperate cards.
Why not just "Creatures are mutants in addition to their other types." and "During your upkeep, each player sacrifices a creature other than ~. Unless you do, tap ~ and it deals 6 damage to you."
12.1.9Flying, Trample
During your upkeep each player puts a counter on a creature they control. Creatures with counters on them are Mutants in addition to their other creature types.
During your upkeep each player sacrifices a mutant creature. Demon Mutant can't be sacrificed this way.
During your upkeep if you can not sacrifice a mutant creature, tap Demon Mutant and it deals 6 damage to you.
The laboratory had to be closed down. Not because of any danger but because the lab ran out of test subjects.
12.1.9When Pious Elementalist comes into play you may pay G. If you do add a Muntant Counter or +1/+1 counter to target creature. Creatures with a Mutant Counter on them are a Mutant in addition to their other creature types.
When Pious Elementalist comes into play you may pay W. If you do remove a counter from target permanent.
12.1.9When Swirrling Vortex comes into play you may pay X.
Swirrling Vortex comes into play with as many +1/+1 counters equal to how many colors were used to pay X.
12.02.02 When CARDNAME resolves you may pay X.
You may tap up to as many target creatures as colors used to pay X. Draw that many cards.
12.02.02 Haste Whenever Renegade attacks, tap target blue creature defending player controls.
Trying out wording it differently but it loses the "or" factor.
12.1.15When Treefolk Assassin unmorphs you may pay X.
If black mana was used to pay X you may destroy a creature blocked or blocking Treefolk Assassin.
If green mana was used to pay X you may prevent all combt damage to treefolk creatures this turn. Morph 2
Reminds me of Shape Stealer.
12.1.13When Amophic Puddle comes into play choose a creature on the battlfield.
X is equal to that creature's power and Y is equal to that creature's toughness.
12.1.11Enchanted Creature has flying.

looses = loses. I'm sorry about getting uptight about spelling, but that one drives me up a wall.
It would still deal 5 damage because once damage and counters are removed / prevented then all damage is already dealt.
I presumed this was supposed to work the same way as the various "If ~ would take damage, instead remove a +1/+1 counter." creatures. But maybe not.
But what would it do to the 3/3? Deal 5 damage or 1 damage? The wording doesn't actually work either way, because the "Whenever" is trying to prevent the damage after it's already happened, but once I understand what you want I can help you find the wording you want.

Wouldn't it remove four counters and prevent up to 4 damage which would mean it would survive as a 1/1?
The second ability is rather confused. Say this has 4 +1/+1 counters on it and is in combat with a 3/3. What are you expecting to happen?

12.1.9Whenever a creature comes into play under an opponent's control put a +1/+1 counter on Gobbling Horror.
Whenever Gobbling Horror is dealt damage remove all +1/+1 counters from Gobbling Horror. Prevent damage up to how mny counters are removed this way.
If Gobbling Horror would deal damage to a player, prevent it. That player looses 1 life.
Gobbling Horror likes to toy with it's prey.
Also dropped it down to a 1/1. Mana cost should probably be updated but probably still needs alot of tweaking.
