Having gone into this fairly blind, I was pleasantly surprised by this one! By the time Sarah and Vanessa were leaving the school I was pretty invested in their relationship, and I think that you did a good job at giving them distinct personalities that weren't too exaggerated or over-the-top. I was also pretty keen to test out what would happen if the relationship reached either the highest or lowest points, and I liked that it was fairly obvious which choice would lead to which change in the relationship.
Unfortunately, this means that I was a little disappointed when I did my second playthrough and realised that it was only the final choice that affected the ending, although I understand that this is probably due to not wanting to introduce scope creep during the span of the jam. The art assets also clashed a bit with the style of the sprites - that being said, they contributed wonderfully to creating the atmosphere of a spooky, gloomy mansion.
Otherwise, it was a great read! I was also really pleased when I got my first ending and the duo were able to make it out without issue, and the explanation of what happened to them afterwards was very heartwarming. You've done a good job with this; great work!
