Things I enjoyed: Clear highlights for object interactions, functional and complete experience. Interesting content: the text for the paintings, the jukebox song curation. Well executed visual assets: the cat audiovisual animation, the rain vfx!
Things I had difficulty with: The door should not have a (not-trigger) collider because it's pushing the character out again when re-entering from outside :) The "Click to interact" text display should hide after the interaction is enabled/while the content text is open, because now they overlap and are hard to read when looking at the painting. When there are UI elements (e.g. close button), the camera control with mouse should be temporarily disabled. Similarly, the permanent UI element (i) does not work well with a first person approach, consider substituting it with a button press (e.g. escape keyboard).
Ideas: Consider adding the painting and song sources to the credits, and adding a url hyperlink on the paintings to redirect to museum or Wikipedia entries. Nice choice adding reload as a button option in the menu - would make more impact if there was user progress with a closing to the story. FPS display is useful for testing but I don't think it offered me much as an end-user.
Very well done! 🐈⬛🌧️ With the addition of a few "binding" elements to move from a sandbox to a narrative approach, this would be a perfect sample for the M110 individual assignment. Great idea adding your github repo!
