I very much enjoy this game and think it'll be awesome in the future. The only problem I have with it is that I can't run it in full screen for some reason.
The only other points of criticism I can think off are travel times not rounded down (as others have already pointed out), some of the times spent that aren't accurate and the fact that you can only see each bathroom peek scene once (took me a while to figure out they went to your picture folder on your phone and aren't viewable at the keyhole anymore). It would be interesting if you kept those in with a chance of seeing a random event once in a while.
What I do like, however, is the fact you pointed out with a textbox that you should retry "lower level" events when you've progressed to the next "tier". If there's one thing I find annoying is that a lot of games require a walkthrough. I mean, it's one thing to map out the optimal path, but if you have to alt-tab after every step (yes, I only have one monitor, fuck off) to see where you have to go next because you'd never figure it out on your own, gets annoying fast (which is why I enjoy ICCreations games since they use the quest system as an in-game walkthrough, why there aren't more RPGM games that use this, I can't understand). But right now, everything flows naturally and you can make do it with trial and error on your own (as it should be). So please, don't put in convoluted quests with weird sidesteps so that a walkthrough would become mandatory. Don't get me wrong, I don't oppose quests, just set the objective in a text message and make the resolution logical and easy to figure out (so please, no "go to the mall at ten exactly to meet with a guy you had no prior knowledge about since no one has ever mentioned him before").
But all in all, a good game and if you keep up the way you're working, you'll be fine.
