the location of the choices is weird, the dialogue is a bit...wonky(i recommend LanguageTool or Grammarly), MC is a silent protagonist, some characters need a restyle(aside the mum, the sister and the neighbour-woman, everyone look like a gremlin). Some bits of the plot make no sense(the sister has to move to a friend's house because her mum can't drive her to school, despite being perfectly capable of taking the train, and she explains it as she is taking the train with MC)
overall it's a cheap alpha, needs to be fixed quite a bit, but i see some potential for a lighthearted story(similar but hopefully different from Solvalley School)
