Only played a little bit so far and navigation is a huge turn-off. It is a chore having to poke arrow after arrow to go to the class each time, for example. Also, most of the time there is a performance issue where it has a delay before recognizing my cursor is over a bubble or an NPC. I know my laptop is not a gaming laptop, but considering I don't have the same issues with much more graphically intense games that use arrows / bubbles to move to new screens I felt I'd let you know. I feel you should make a fast travel management for places you have been to before like most VNs use - if that isn't a feature already that unlocks later and I've yet to get to (I.E. a series of sub-areas, such as inside the school you could pick the room from a list of rooms previously visited). You could also benefit from a guide to let players know what characters are in that area when you pick it from the map, such as character heads of characters you can interact with under the school on the map. I made it to day 1 and gave up for now because I felt too bored and annoyed just poking bubbles aimlessly for no return, especially with the latency issue I mentioned that happens with the bubbles and characters 'lighting up' before left-clicking does anything.
Also, the entire introduction of Skyler felt off for several reasons I can't state without giving spoilers. Half or more of it just made no sense contextually.
