Well... it ain't easy, being a mouse. In this game, a mouse recounts the many events in his life before he goes with... whatever a mouse calls the grim reaper.
It was actually an interesting read. The writing has a melancholy tone to it, and really got me thinking about those experiences a mouse might face. Experiences like getting abandoned by a parent, being caught by a human, falling in love with a mate and so on. You get a choice of cards to pick to see each experience (it's a bit hard to handle those cards on mobile screen) and to unlock all the content, multiple replays will be needed. Some of those experiences offer choices which provide a bit of extra story interactivity. The black and white color scheme for the background art and the font also help with conveying the vibe.
I recommend taking a look, drawing those cards and looking back before it's time to go well... where a mouse goes at the end of days.
