Floor 5 is certainly a marathon. Has a nice epic feel to it. If you do allow extended runs, just doing it over and over again with an ever strengthening dragon would prove a nice challenge.
Of course, it's so big it didn't entirely fit on my phone screen, prompting me to mess around until I figured out how to pan the floor, and while I was messing around I found that little secret xD
... speaking of which, that secret's always been there? You mean I could've cheesed the Ascetic achievements instead of doing them the hard fair way? Woe is me. /jk
I noticed you added a way to get money directly from the secret god menu btw. Having that and the "reroll" that makes the shop sell all items is certainly going to make it easier for me to test items when I update my guide.
EDIT: Also, am I imagining it, or did you make it harder to accidentally stumble on the god menu? Feels like now I have try to access it a few times before it actually opens, but once it opens once I can toggle it at will.
