There's a lot to like here, but too AI-generated for me. The pixel art for Tokyo & Hong Kong don't use proper Chinese/Japanese characters. The pulsating badges in the non-pixel UI are also pretty AI-indicative in a way that is distracting.
I would have been very impressed if it made pixel art for cities on demand. If I were able to put in my hometown and see a delightful pixel art memory, I'd swoon and point to it and say "wow wee LLMs are pretty dope aren't they", but instead I'm just thinking this is yet another shallow project which will be abandoned tomorrow.
