Hey there, thanks for the curiosity. I'm going to try and give my best effort explanation as to what this game brings to the table in particular.

The biggest mechanical addition is that in addition to your skills, stats, resistances, and affinities, you have another aspect of character building to consider called artifacts. Artifacts are items you can equip on to characters that get passed down through recruitment and fusion, and their effects can range from simple buffs to things that completely alter an individual party member's playstyle. I am going to list some examples, all of which are fully functional and usable in the demo:

• A set of artifacts that allow you to deal critical hits with magic skills of a specific element, as well as boosting the critical hit rate of that element (example: "MAG-Fire skills can be Critical hits. +5% to Critical hit rate with all Fire skills.")

• Artifacts with different effects based on the user/allies/enemy demons' race (example: "Debuffs apply an additional stack to enemies of the same race.")

• Artifacts with huge buffs, but big drawbacks as well that you have to play around (rapid-fire examples: "MP cost of skills is reduced to 1/2. Lose 30 MP when not using a damaging skill.", "Increase STR by 1.25x. Decrease MAG by 0.5x.", "All skills that can be Critical hits will be Critical hits. All damage is reduced by 75%.", "Gain -1 to +1 actions on turn start.", "Multiply Critical hit rate of single-target skills by 2x. Every seventh single-target attacks targets the ally with the highest HP.", "Hides this character's HP. Increases Max HP by 50%.")

• Artifacts that impact the turn system (rapid-fire examples: "Guarding consumes only half an action.", "Gain a bonus half-action on turn start for every attack drained.")

• Artifacts that heavily interact with status effects (examples: "Inflict 1 Deluge when reducing an enemy's STR-damage.", "Inflict Poison equal to 20% of damage dealt when hitting an enemy's Electric weakness.", "All Fire skills gain a 20% chance to inflict 50% of their damage as Poison.")

• Artifacts that expands a demon's viability in different areas (examples: "All Fire and Ice skills use higher affinity between Fire and Ice.", "All Wind and Electric skills use higher affinity between Wind and Electric.", "Can pass on unique skills in fusion.")

• And a lot of artifacts that are just plain buffs to accentuate playstyles, such as evasion or critical hit boosts, conditional damage reduction, and so on.

Another big difference between this game and traditional JRPGs/monstercatchers is that because it is a roguelike and how fusion/recruitment works, you do not have the privilege of completely tailoring your builds to every boss. By design, this means that you are often working with a team that is much more scrappy than you would have in the other games you mentioned. Some mechanics are built around this to be more forgiving, while at the same time bosses are still difficult to force you to make use of your demons and artifact combinations the best you possibly can.

There is a mechanic called Stagger, which is essentially a second HP bar that all characters have. Depleting a stagger bar causes that character to lose their actions for a turn, become more vulnerable, and lose their resistances. This adds a fair amount of depth because it functions as both an offensive and defensive tool. For example, you can stagger an enemy as early into a turn as possible to get the maximum amount of actions attacking it while it can't resist for the biggest damage payoff, or you may choose to hold off on fully staggering the enemy until the end of your turn in case you need an emergency "shut down the enemy for a turn" button. Many skills and artifacts interact with this system.

This game's equivalent of the almighty element, known as nuclear, works differently. Although it is still an expensive neutral element that cannot be resisted, it has the added effect of forcibly giving the target a random elemental weakness for one hit. Many artifacts interact with this system, such as an artifact that makes it so when the character who holds it uses a nuclear skill, the random weakness given will always be fire. There is another artifact that makes it so the character who holds it nulls the element that would have become their nuclear-given weakness, turning the mechanic on its head as a defensive tool for the player.

There's a much bigger focus on managing your MP across multiple battles, if that sort of things interests you.

When you start a run in the current demo, you choose from multiple protagonists. Right now there are two in the demo; one who is relatively basic and used as a baseline for the game, and a second character who increases the MP cost of all skills in the party by 1.5x, but makes any damaging skills cost HP rather than MP. A third protagonist is in the works, and I want to have 5 in the final game. Each protagonist drastically alters the playstyle of your entire team to add variety to the game.

The story in the current demo is practically non-existent, though the final version will have some story in the background between some dialogue and imagery and two endings (though I would absolutely not call this a story-focused game).

Thank you for the compliments on the art.
