[android] [2010s] Looking for a lost mobile pixel-art game — female protagonist, afterlife city, tragic flashback ending

Hi. I'm trying to find a very obscure old mobile indie game. It might no longer exist, but I'm hoping someone remembers it.

What I remember:

• Mobile game (played on phone, early–mid 2010s)
• Pixel art
• Story-driven, slow-paced
• Female protagonist
• Setting: an abandoned city that is later revealed to be the afterlife / a limbo after death
• The protagonist meets another person there and they team up to survive / move forward
• Final twist: the scene where they shoot each other is actually a flashback
• At the end she realizes she had already died, and that they shot each other simultaneously in real life

It felt very small, personal, almost like a game jam or experimental project. I haven't been able to find any trace of it online, so it might have been removed from stores.

If this sounds familiar to anyone — even if you only remember the developer, a screenshot, or where it was published — any detail would help a lot. Thank you.
