The animations leave something to be desired, but I actually found the GAME to be interesting.
It is INCREDIBLY punishing at the start.
When your main character is NOT "Happy", Jog.
There is NO punishment for letting the girls stats reach 0 (yet) so you can absolutely work them to the bone (I tried to keep their stats up to progress their stories but given the game's structure, I could have just focused on the store until I was making bank)
ABSOLUTELY spend all your money on new recipe books (EXCLUSIVELY Recipe 1 books, you literally can't use the other ones in current patch) You'll eventually reach level 2 recipes which are so obscenely better than recipe 1s (and also have place holder text) that you'll be making 1200+ a day.
When your main character gets 80+ "Heart" MAKE SURE TO JACK OFF. The penalty for having a wet dream is huge, and jacking off improves your mood dramatically.
Only buy the second Mood treat and Ramen. The math just makes them better than all other options even if they're the most expensive, they're the most efficient.
Next to none of the incremental books for sale are worth it. you're better putting your money to more recipes.
I DID cause the game to hang when researching more recipes. I think because they're placeholder they might be prone to glitches. Sadly I hadn't saved in a LONG time so I'm putting the game down until the next patch comes out.
I would personally like an "ecstatic" Mood to indicate "mood is maximum" because Happy, Normal, and Sad are all ranges, but Miserable is a bottoming out, and given work consumes atleast 11 mood, you are CONSTANTLY losing mood (which inhibits your ability to talk to the girls, or even research/work part-time), so the gameplay loop is optimized to be:
Work -> Jog -> (repeat until Wednesday) -> Jog until Happy -> "Go out" to buy recipe books -> Research recipe books until Friday -> Repeat
IF there is going to be a larger penalty to the girls being miserable and dead tired, the difficulty of the game needs to come WAY down. I was barely scraping by in trying to keep the girls happy and energetic.
By the time I had figured out the loop I had 400+ energy and NOTHING TO DO WITH IT. My MOOD was dictating my actions and not my energy. Energy basically became a useless stat, as the Mood gain from Jogging was the most important part.
