I've downloaded build 0.19, and I've noticed two things. Firstly, if you skip the tutorial (haven't tested if it happens starting the game other ways), then Brenda doesn't have a character model when you first enter the school, she's invisible.
Second, Brenda's Route gets stuck at the stage where it asks you to "Talk to her at noon again" - no matter how many times you talk to her at noon, it doesn't progress the route any further. I've tested this on each day where you can actually talk to her at noon, and none of them work.
