I completed the game.
I don't mind the art style but the game is quite complete with a rudimentary yet functional inventory system and a very interesting dungeon featuring quite detailed environment which you need to progressively open by navigating between the two, both furnished, realms and looking for the keycards, a tool and even a code. Obviously the game implements the theme pretty well.
Be careful, in theory I like the detailed control options but in practice I almost gave up because 'H' does nothing in AZERTY mode and I got stuck in the beginning as a result because I could not know what to do without the control chart, it flowed after restarting in QWERTY mode.
Very fun game, thanks for sharing.
