I’m thankful for the free game and I hope that what I’m going to say will sound like constructive criticism, instead of whining.
The “semi-profile” view of the area makes it hard to know when to press Space to pull girls into the lockers, and for some reason the timing is even trickier in this game than in your earlier games.
The other games had “generic” characters. I think this works better than having a market full of copies of the same waifus, the waifus should “feel” special. IMO each waifu should appear once a day, and catching her should give you some bonus.
Esc should close any and all pop-ups, and bring up the menu if there’s no pop-up.
It is not clear at all why higher shelves would be better.
It feels wrong to have girls who climaxed to report you, as they see other girls leaving the locker.
Instead of “click here to continue” between days, it would be better to click anywhere on the screen to proceed. Or, if you must require clicking a specific area of the screen, make it look like a button.
“Speed up” should be something that you hold down, not a clickfest.
Catching the exact same girl multiple times is fun. Specially when she shows some progression: ragged clothes, fluids, swelling…
Feature suggestion: fertilisation. It doesn’t need to be fancy; just an image/animation pop-up of an ovum being surrounded by sperm cells, and pierced by one. If it’s uncommon enough, and associated with some bonus, it gets really nice. (Bonus points if the same girl pops up the next days, with a preg belly.)
I won’t suggest to have the tentacles climaxing because I bet that you have it planned out anyway.
Finally, I get that the Unity fiasco forced you guys to change the engine, but if you concentrated the dev time into a single game, the end result would be probably great. (And it would sell better too.)
