The music and art so far are lovely and set a great mood. I like the character art especially and the doors as level selectors. The game play though I still find a bit confusing.
The tutorial feels too text-heavy; I would prefer to be doing more in order to learn the controls, rather than read about them at length. The downside of this is also that it names a bunch of things in text and I still don't know what to do, because it doesn't show them. I'd rather have the game do things like highlight a button I have to press, with perhaps a single sentence explaining what it does, so I can see the effect of those mechanics immediately and understand how to use them. I find myself just pressing things a bit too randomly instead.
A small nitpick is that the text moves a bit too slow. I know you can double-click to write it out instantly, but for the "talking" effect it could still be a little faster.
I see you've gotten a bunch of feedback about the tutorial already and I agree it can use some work in order to get into the game flow quicker and easier. But the game's general great vibe and promise of what's to come definitely invites you into wanting to play.
