I wasn't able to progress past exploring the map. I went through your source code and found that Home is bound to ESC and Inventory is bound to E, neither of these keys did anything for me. Maybe you had to unlock them by completing some task? If that is the case I could not find it for the life of me. This is probably a me problem though given everyone else here could play. Oh well. I loved the art style and music, incredibly charming game, dialogue was cute and very nostalgic. nice job :)
