Kemono Friends

This was the first game in the Kemono Friends series. This side-scrolling RPG puts the player in the role of a human with amnesia who finds themselves in a massive zoo known as Japari Park. Upon meeting park guide Mirai and a Friend named Serval, they learn that the park is currently closed because of an infestation of strange creatures known as Ceruleans. As they journey through the park, the party ends up in conflict with the Ceruleans.

This game was infamously shut down in December, 2016, two months before the release of the anime nominally based on it.
