Fair warning that I will be biased towards more transformation type content and as a result post bad-end content involving said transformations as well. I like the ideas you have proposed and agree that time limits tend not to work out very well when implemented so another solution may be necessary. Since this area already has more of a desert/Egyptian theme to it maybe adding a Nile like river nearby might give you more options to work with, would love to see some croc girls myself (or maybe save those for a sewer level?). For the most part though I have enjoyed the peril’s you have chosen to add into the game and trust you to do what you think is best although having said that I will always support more mongirl/transformation type stuff.
PS: I really hope the name of the sex toy shop in the city is a hint of things to come ;)
