I reached the area with an enemy and two doors, if I understood your comments then I think I played what's accessible in the current version, thrice actually.
I have to say movement feels specially good in this one, that I won't switch to instant movement is telling. It looks great and consistent and you've got quite some functional systems. I really like the transparency of the illusionary wall, it's perfect. Combat which is there is good enough, I like that the enemies don't take too much time to defeat.
I actually really like gaining XP for visiting a new tile. What I think though, as it seems you'll work further on the game, is that you could add an option to disable displaying it, and possibly some other feedback popping-up as well but specially this one. I have no strong opinion either way about it myself but I think some people will enjoy the arcade-ish feel it adds while some other persons will feel it breaks immersion.
I don't know if you thought about it and maybe it's just me but this kind of real-time combat system shines and feels satisfying to me as soon as enemies can fall into holes, get onto spike traps or on the way of fireball traps (also if I can close doors onto their head but as doors fill a wall and not a tile in your game then it's likely not relevant here).
The game's promising, thanks for sharing, I'm going to play the fixed the version after the jam.
