First off, Yes, you can play this game on Kongregate or Newgrounds (or possibly Matt's DA), however the version you play will not be this one.
In other words, No, this isn't the same game you can play on the sites I previously mentioned.
What you'll play is indeed an RPG akin to the old days of Final Fantasy, when Combat wasn't real-time combat with before-use cooldowns.
To those unfamiliar with the Epic Battle Fantasy series (namely the ones with actual story elements) This is an RPG game with tons of funny things here and there, self-referencing humor, and things that reference alot of other things.
So basically the story so far is there's 3 heroes.
One is Matt, who jsut wants food, like swords and piracy... He's also a pirate.. Did I mention he has a guitar and likes Death Metal? I jsut did, you're welcome, reason 1 to buy this game.
There's Natalie, whose powers are in her awe-inspiring magical powers, witty remarks, different mindset of the others, and her boobs. No seriously she's kinda the "Big boobed girl cliche" of the series, though she's hilariously not jsut eye candy, dishing out the sage advice and owning remarks. But even more seriously she's literally the only one who can decently heal and revive party members. She's kinda the most important character combat-wise.
There's Lance who is a military guy.
In a world filled with big demons (like the last villain you kill in #3), sapient cats with no limbs able to wield weapons via unexplained telepathy powers, elementals, magic, Lance is the one who kills things with overwhelming firepower. Seriously though, he melts those who are weak to bomb-type attacks and even has decent fire and electric attacks.
There's a 4th character, a huntress druid girl for Natalie to relate to.
This game also has achievements alongside the medals of the game, giving you elevated bragging rights.
Your progress on this version won't be wiped by clearing your cache or cookies.
There's what I call a Shamievement, an achievement that's more or less a badge of shame like Duke Nukem Forever's Turd Burglar. You'll be rewarded for being a perv by this, though it really could be worse, so in terms of them, it's really not bad.
Here's the part you care about though... The exclusive content.
This version has more weapons, and more items in general, save for crafting materials (i think) and this game has an entire area called Challenge Mountain. This area is literally filled with enemy encounters which all have 8 enemy encounters each and stronger versions of the bosses in the game which are WAY harder to kill.
Every enemy in thise area scales with level, which means you can get past all enemies at level 1, though you do need quest items like the axe or battery to get past some bits.
How does this game fare? Well for someone who played the first half 3 times on Kongregate, I can say the game fares really awesomely. I mean... never did I once say "Oh god not this part again" or the infamous "Why can't I just skip this" and I'm one of many who found Diablo 2 monotonous after Normal difficulty.
This game is very fun, has some funny elements and even gets challenging properly without feeling unfair. This game doesn't have any difficulty spikes... until the final area, but around then you're ready for it. This game is simply a blast, the only thing stopping me from playing it is just the simple fact I'm feeling a bit bored of RPGs in general.
Alongside such big titles like Final Fantasy, Diablo, Torchlight, and even anything else you could really think of, this game holds it's own ground. The game is honestly fairly unique in my opinion.
This game in my books gets a 7/10. It's pretty good honestly, and I'd easily recommend it to anyone who likes Turn-Based games and RPGs, Despite the fact you can play the game on Kongregate with 30% less content for free.
