i think the idea is good and i had fun. the VN is what kept me interested in going, but the writing could use some work
there's some small issues and some bigger issues. ill start with the small ones
the camera angle needs work. the important part (how many people are waiting + their mood) is squished at the bottom of the screen. the unimportant part (everything higher than the bar boxes) takes up half of the screen and contributes nothing.
there is no penalty for using the skills off cooldown. i assume there's some sort of morale for the girls, but just clicking anything when possible didn't give me any penalty. for example, you probably should have OVERDRIVE work off the cooldown, but if you use it consecutively, this could cause anger or diminishing bonuses until eventually it amounts to nothing.
there is too much text (yapping) during gameplay. it obstructs the actually important events, like fire or wisps or the patience of patrons. i get this will get replaced during devtime if you continue on this project, but eye clutter is bad even during programmer-art, and it felt it was quite cluttered especially with a lot of patrons out and about
now for the more important / bigger part:
the gameplay is just click a bunch, do nothing, click a bunch. i did dumb it down in speech but there needs to be a non click action. a start would be to 'pick up and manually carry out' an annoying patron- a click and drag action breaks up the pace. honestly worth looking into is the Wasteland Bites game, with how they use multiple types of mouse actions to simulate different actions. dousing fires can take 5 clicks instead of 1, cleaning 'stains' can be a swipe, etc. there needs to be some break in the pace where the user does something different than just press buttons or click, since the repetition causes boredom even if the visuals keep changing
feedback aside, i had fun. your art is good and you could make this work, if you improved the writing a bit and added more variety to gameplay.
keep it up! i figure this is just a DD69 sideject, but still, maybe its something you can come back to after maid cafe sim stuff
