Hi, thank you for playing our game! Yes in Ren’Py, which is basically a library of Python used to create Visual Novels, there is a built-in notification feature that can be used in game for like achievements, etc. Yes you’re correct, in fact the notifications in our game is the character’s (Lupen) way of remembering the events that are unfolding in the casino and the characters’ inner thoughts. We definitely wanted to expand on this feature, such as saving his memories as achievements and using them when you replay the game to remember and recall certain events, but simply put, we ran out of development time (I’m also new to Ren’Py). We hope to implement more features in the future!
