The Boss Project

Preamble
I'm departing from my usual method of reviewing for this one. Boss Project is too short and too centered on one feature to hold it to the same regard as a proper completed game. It'd be like scrutinizing the motorcycle minigame in Final Fantasy 7 as compared to actual Final Fantasy 7.
So think of this as a combination Lets-Play and Tip Guide instead.

Aesthetics and Whatnot
The moment a player hits New Game, they're dropped into an 8-bit castle. I grew up with 8-bit so it's all good by me. The music is a midi rendition of 8-bit music too. Rock on. Let the time portal to my youth open.
Until I enter battle, where the bosses all have Grandia boss BGMs. So much for the element of nostalgia. At least they're some pretty badass tunes.

The Posse
One of my complaints (and many others' too) with Ephiam's game Eternal Paradise was being given a party of level 40s with all kinds of equipment and skills that do I-don't-know-what. As if I was handed someone else's Save file, it felt like Lufia and the Fortress of Doom, except it's just Fortress of Doom.
Well, Boss Project's guys can kick Eternal Paradise's guys asses. This heroic band of Level 90s come equipped with phenomenal gear, wrenched from the cold dead hands of their guardians and brought to surface from the bowels of hell, or maybe they were given to them by Gods as part of the storyline, or maybe they were just purchased for unfathomable zillions from a store. Whatever ordeals were undertaken, they're armed to the teeth and ready to steamroll the ultimate forces of darkness.

Let's meet the heroes.
The Knight - True to the 8-bit era, the brute force physical fighter has no magic. He just Fights and uses items if needed. He also sucks because...
The Red - Red's Attack stat is only 33 points shy of The Knight's 999, he's the second fastest in the party (a full 30% faster than Knight), his MP is halved thanks to an item, and he's the only one with Haste and Slow spells. Basically, he turns Knight into better-than-nothing roster filler by comparison. If party selection were a thing, I'd have two Reds.
The Mage - The archetypal black mage. The inclusion of black magic Items in your inventory kind of makes him unnecessary, but his MP-based variants of elemental damage are more powerful, so he has that going for him. I'd still rather have a third Red.
The Cleric - Healers are never not useful. Again, the healing items in your inventory can theoretically make him/her redundant, but in Boss Project they're finite and it's always nice to have a person dedicated to heal bombing anyway. As a bonus, he/she has a holy-element spell which came in handy. But I'd still rather have a fourth Red.

How Did I Fare?

Beelzebub and Dark Soul
Parties Slain : 1
I only died because I forgot to switch the ATB from Active to Wait. As I was navigating menus, seeing what I had available, these two were laying into me. A few status ailments and several thousand damage later, there was no turning that ship around so I let myself be Game Over'ed.

Back for the real deal I came. My rule of thumb, whenever I fight a boss with multiple parts, is to never target the "main" until it's all that's left. So I went after Beezlebub's friend Dark Soul. It turns out Dark Soul is the only one you need to target because Beelzebub disintegrated with him.
My strategy was pretty simple jRPG fare : Haste and Regen my party members, Slow the enemy, and use each guy's most effective attacks. While everyone else was doing 2500-3500 damage with Fire magic/items, The Knight attacked Dark Soul for a less-than-whopping 600 damage. hmmm... must be strong vs Physical, so Knight used Fire items too.

The Lord
Parties Slain : 2
As the next battle raged, The Lord started accumulating these little things called Death Tokens. I wasn't sure what they were, but I figured they were contributing to his completely wrecking my party, so I targeted them a bunch of times. Big mistake. They don't do squat. All those turns were wasted, and then one of The Lord's 7-Hit skills brought my team down.

In the second attempt, I rightly ignored the Death Tokens, but erroneously focused on building my defense so his multi-hit physicals wouldn't be so lethal. Once he hit 5 Death Tokens, he insta-obliterated me, FF4 Bahamut style.
Magic : The Gathering much? At the start of your turn, put a Death Token on The Lord. Tap: Remove 5 Death Tokens from The Lord. Target player loses the game.

Third time's the charm. Knowing now what must be done, I Hasted and wailed on him with elemental magic/items. Fire seemed to do slightly more, but I wanted to conserve them. The Knight tried fighting again, and did 600 again. "Wow. 600, huh. That's... that's it?" With Attack Up he could muster 1300, still not matching a magic item's 2000+, and then the Attack Up effect was dispelled.....

Dark Knight (aka Giant)
Parties Slain : 0
The Dark Knight (aka Giant) bought the farm on my first try.
The rule of thumb applied here too : Never target the "main" until it's the only one left. In this case, the "main" was the Body, conveniently under a state of UltWall in case I needed another cue. Okay, Sword first, then Head.
I Hasted my party, Slowed the Sword and Head, and killed them without much trouble. He had a Field Shift skill which dispelled my Haste and inflicted ConstSlow, but no worries : Re-Hasting partially counteracts it so now I'm back to regular speed. Lightning seemed to be the element of the day, so down those two went under my KaZappa'ing frenzy.

The Body was immune to elemental damage which actually made the otherwise useless Knight, useful. With a little help from The Cleric's Attack Up spell, he was doing his part to bring down the last piece of the pie. Good job, Knight. Red was doing the exact same damage, and he can do a heck of a lot more than you, but you did your best. Thanks for coming out.

****Duh Duh Duh Duuuuuuh****

Chaos
Parties Slain : 2
Ephiam, you sunuvabitch! You said there were only three bosses in the game description!
Yeah, defeating those three opens a locked door, but I just kinda figured it was a door to, you know, the ending or something. An imprisoned Goddess, or a holy relic, or a stairway to heaven.

My mages were low on MP and I had no Ethers left. That wasn't about to stop me. I'm here to Beat the Boss Project, and that's what I did.
I thought for sure I was going to need a fourth try, but I managed to just barely squeak by. All MP depleted, all elemental tokens gone, 2 Super Potions and 3 Giga Potions left, I poured all my efforts into Knight and Red's physical attacks in the end. The Knight redeemed himself in this battle, but only partially. He missed a few times, never criticalled like Red did, and to add insult to injury, it was Red who dealt the final blow.

And thus, Boss Project came to an end with a short, nondescript ending sequence. Wait, is that Venaitura?

Tips and Tricks
The Knight's attack blows, but is still needed to win. Use him on Beelzebub (Dark Soul, rather) and the Giant, and save the Tokens for the other two.
And remember that Haste and Regen never wear off. Even if you die :D They can be dispelled though.
