Fun game!
It took me a while for me to get that you're supposed to be learning the room layouts and figuring out optimal ways to traverse them
The dungeons started feeling a bit labyrinthic at babysteps++ but that's just me meeting unfamiliar rooms while battling the clock, it's indicative of the kind of complexity that makes roguelites replayable.
Maybe a map showing already explored rooms would help mitigate the confusion, and imo interacting with the magic mirror's target shouldn't ask you for confirmation beyond babystep dungeons.
Of course it's missing the non-placeholder art that would make the dungeons worth grinding, but I guess that comes later
