Hi Blended Cookie! I appreciate the thoughtful and kind comment. Yeah, the procedural generation algorithm still sometimes spits out odd structures (that I am still fiddling with!) and one of them is the ‘door to nowhere’ which I believe comes about due to how I place ’themed’ rooms around the map during generation.
Also, thanks for the idea with the enemy catalog; was definitely something I’ve been thinking about (even since the very first version of Flemenco) but have never gotten around to! This will be in the next update. Also, in terms of stat upgrades, these will be rebalanced and changed (with more progression options for the main game mode) in the next update.
Thanks for playing!
