I downloaded the Demo because the art looked really nice and even after starting the game, that's still the highlight about your game imo. The rest isn't great, unfortunately. The sounds, music, and so on aren't terrible but feel like a 2000s flash game, rather generic. The actually terrible part are the controls. Both in menus and in game, everything is delayed, sometimes ignored entirely and it just feels super unsatisfying.

I'm disappointed if great art like that goes to waste. I think it was a bad choice to release a demo of the game in this state, unless you are actively looking for feedback.
