After finally trying this today, I'll say: Definitely like the content so far. Will say the RNG on the food searching is a bit obnoxious, but once you just learn to save/load before going out, you can get the W on searches easier; it still makes it less than desirable, but I'm hoping Intelligence can help improve searches in the future or something (idk, throwing out ideas here besides just removing the RNG). Would also be nice if Mark had a chance to successfully get food on days where you opt to do Tiffany/Alex content instead to progress.
Hoping the following updates focus more on just Alex x Tiffany, cuz the majority of the actual sex was Mark x Tiffany so far. Finally, I don't see much use for bullets other than the one random zombie mob encounter that doesn't do much other than keep Mark from getting injured.
Other than that, keep up the good work, I think this has potential.
