Great art with a lot of potential. I don't know if I am a big fan of the timer tho. I agree that some notable Tokyo locations would be really cool for this; Roppongi Hills, Shinjuku's shopping streets, Shibuya crossing or something similar. If you want a timer you could make it a day to night cycle where location and lighting helped build scores. But regardless; cute game.
Thanks a ton for trying it!
We had a lot of similar ideas for a larger version of this game. We imagined a subway system where you chose what neighborhood of Tokyo you wanted to take photos in and each neighborhood would have its own vibe. This version was a proof of concept for us, and if enough people like it we might consider adding more content!
