Undertale meets Final Fantasy meets Legend of Zelda. This is one demo that has to be played to be believed.
Tl;dr - I freakin' love this game.
I'm bombarded by tons of inspiration when playing this: Undertale. Final Fantasy. OG Legend of Zelda. And yet, this has an identity all its own.
The game plays like a mix of Undertale and Final Fantasy. You have the overworld which can shift between top-down to a pseudo-2D perspective. Encounters happen like Zelda II: The Adventure of Link where you have to touch the enemies; you can also hit them with an axe to gain an advantage on your first turn. The actual battles play out in a mix of the three games: you choose actions like UT and FF, you attack and evade like Zelda II. Throw in some puzzles and everything meshes surprisingly well.
Graphically, it looks like a retro 8-bit game, somewhere between Shovel Knight and Deltarune.
The soundtrack is great, but I feel like it jumps between 8-bit NES and 16-bit Genesis/Mega Drive too willy-nilly. On paper, this isn't an issue for me as I love both sound fonts. I would like to see either a better transition between the two or have the game begin 8-bit and work its way to 16-bit. That's just me nit-picking.
O:HLE controls just like a retro RPG would - move out of battle on the cardinal plane, in battle like a platformer. This game deserves to be played with a good D-Pad, and I suspect it would be good on KB/M as well.
While I've only made it through the first part of the demo, I have the sneaking suspicion that there's much more than what meets the eye. I'm awaiting further demos and information about this game with giddy anticipation.
