This is a really interesting concept, though i feel it needs more itteration and time to bake. The artstyle doesn't resonate with me at present, the pieces on the gameboard style is really interesting though i think the shading method makes it feel very plastic. As for the gameplay i wish i shared a turn with enemies, and they moved in more clear and predictable patterns. at present i would move to try and avoid an enemy only for them to jump into the space next to the space i'm moving into and instantly dealing damage to me, which felt a bit unfair. The tilebased map is an amazing concept, though i wish that the tiles weren't just generated individually, but in sets, the maze map feels claustrophobic and frustrating at times, dealing garunteed damage, where as the open map has the opposite problem of no where to hide from enemies. If structures generated whole buildings or larger alcoves than singular wall tiles, i think that would feel more interesting and engaging to strategize with.
But that's just my opinion, the dementia mechanic is super cool! being able to walk away and reset a obstacle to get it out of the road is really interesting, and i can see that being expanded upon if you itterate on this idea. All in all, really really cool design c:
