Nicely done! I am usually not a big fan of deck-building games in general, but I am still enjoying yours regardless. I also loved the graphic, tone and especially the colour palette, seems very fitting! Sadly I encountered the soft lock you mentioned and it was just disappointing, given that the run is going strong. But oh well, I was warned not to do, so that's one on me.
As for small nitpicks, I would say the doorways are quite blend-in into the background, such that at first I just don't know what to click. It surely would be much better if the interactable elements stand out a bit more.
Other than that, good job! Really enjoyed it!
