Cool, the game's getting there.
The tutorial used to be serviceable, now it's also elegant. I think the last screen is still a pop-up which is a bit of a shame (https://imgur.com/8BLCsEy), don't hesitate to use the same inteface instead of a pop-up for the Victory screen as well.
I think it's still possible to get stuck behind an empty tile, it was in the entrance room of an area so it was not a case of being in the limit between two areas. By the way in most cases it does not matter but the transition between different parts can be annoying when you can't see a monster above while you're fighting against it.
I got this bug twice more or less at the same time and in the same place (and never otherwise) : https://imgur.com/bZuX1gb.
I think the only thing which is not that fun is that you can simply put your item on the floor then hide behind it, using it as a barricade, and the enemies can't do anything and will just wait to be killed. I'm not sure what the good solution is but I think that items not blocking the enemies at all would at very least not be worse.
Good job, I hope my points are decipherable enough.
