I'm not sure if it was just on my end but the mouse motion is a bit finnicky while playing on the web, but I still managed to reach the top and that last photograph. I'd recommend making a pc build as well(windows, mac, linux) as I believe the mouse movement issue are much less in those exports from my experience.
That aside, I really like the concept of the photograph capturing the past, having a limited amount of shots being the countdown. The atmosphere is well and I'd say Narrative is where this game is strongest / has its strongest potential if developed further. Its a pretty unique game, would love to see more from this.
