You put us all to shame! Incredibly well polished, and really nice presentation, 4th wall breaking with how you set it up with the itch page. Top marks from me.
My partner and I played through several rounds, she loved it. One nit is that we didn’t realize that, unlike we as the player, the invisible cat moves differently (ie they can stop on the door and vents, whereas as a player one move travels all the way through a door to the other side). But, we figured out too which is part of the puzzle of it all I suppose. Could also be nice if there was a way to avoid excessive clicks / moving the mouse to position for the next action. The turn counter idea on the left is super neat and clean, but maybe some keyboard shortcuts (or a way to just hover over the character itself to perform any action based on the context of the turn step) would make it more enjoyable.
