Cool game! Trying to piece together her routine and habits based on the clues from different days was a cool mechanic! And I feel like I figured it out just in time for the week to be over, which is good gameplay, mind you. And the first scene of seeing her breast expansion is well-written. I look forward to seeing more of it!
One critique I'd have is that it's not established what Suspicion does, and what is "too much". There's a few times where I considered sticking with an option I knew worked, but raised suspicion (or at least, I assume raised it) rather than test more for a less-suspicious option, but not knowing how much is too much suspicion stopped me from doing that (which, I guess is a good thing, depending on how you look at it? Since you want to encourage players to try more options.)
