Downloaded because the art looked nice & I liked management type games, but was disappointed with what I found.
TL;DR game is a time waster. It's slow & tedious, plus--while not game breaking--may be buggy. IMO, only play if you can get past this.
Game flow:
0. After the intro, you're dropped onto the hotel map, I suggest you click the ? & read the tutorial 1st.
1. Gameplay is idle-ish, with it's energy management & "daily" resource collection
-- Which, imo, is poorly done: lumber & mining takes 1 en each; giving you 50 (skip) or around 100 if you play the mini-game (half-circle timing bullseye). Doesn't really matter which you do, since your main bottleneck will be gold (50 before upgrades), until you get going.
2. Pass the time (3: morn, noon, night) after expending energy & some events may crop up.
3. Collect the hearts(limited & is slow as heck) in some touching mini-game--If you have trouble, similar to start of game, click the ?; tip: you don't actually have to move for them to increase, so after it starts to tick, can just hold & wait it out but, as said, it's limited/capped.
3.1: Used to purchase upgrades that's supposed to speed up the game -- A problem is it might be bugged; the 1st increase doesn't net you anything, so you'll probably end up w/ 994 (instead of 1k) for the 1st girl (and so on).
3.5 Most of the heart upgrades seem unnecessary. Imo, only the energy one is useful.
Resources? As mentioned, (at least in the beginning) gold is the main bottleneck, & the upgrade only increases gain by 25% ea while being exponential in cost.
Relationship? Same as resources, increases by percentage. Problem? It's capped, either by energy or how much heart you can earn. Thus the only one that might be useful is the answers, but that cost too much to use limited resources on.
4. Now you have to split how you spend energy: either talking to the girl/s or on collecting resources (for room building/upgrades)
4.5 - Though the girls' event--viewable w/ the "people" icon--appears as long as you fulfill the requirements, you'll probably want to meet them before the designated day.
5. To unlock more girls, you either need to build rooms or wait for certain days (aka progress w/ certain girls or event trigger)
v1.0 - There's also some bugs in the game, such as (already mentioned) heart, or the 1st girl's day 5 event netting some (think it was) [Maid#3 code] for the whole of it (before it toss you into some strip & touch mini-game).
