We're so glad you liked the narrative and artwork!
Re: Polaroids - They influence what you talk about/how the break-up goes (e.g., if you choose to remember negative stuff, you say meaner things. There are 4 different types of sentiments that can colour the final conversation), but unfortunately we didn't have enough playtesting time to make that system feel noticeable and work as intended. The different outcomes are still there, but admittedly too hard to achieve/notice.
