I saw this game while scrolling the Spooktober tag on Twitter, and the soft-but-graphic style left such a strong impression on me that I had to play :) I love how distinctive the characters are--Grace and Nerd Girl are especially cute!
I'm not sure which ending I got out of the four, but it ended on a bittersweet (and satisfying) note that did feel very reminiscent of watching a horror movie. I will definitely revisit to see if I can get some of the other endings.
There were a few points where I struggled to interact with objects even when I thought I was standing close enough to them, so if possible, I might suggest expanding the "range" a bit (unsure if this is the right term--I'm an artist, not a programmer lol). I also think it could be fun if more descriptions were available for items in the environment to add some more immersion--things like the postcard racks in the lobby, the cars in the parking lot, etc.
My only other note was that there were some inconsistencies with the English translation; the one that stood out to me most was that one character name was sometimes spelled two different ways (Roxanne/Roxann). That all said, I think this was a fantastic jam game, and I'm so glad I played it! Excellent work!
