This was really good!
(Spoilers ahead!)
The two endings were both amazing. The one on the left - the one where the black hole destroys everything - it seems like a metaphor for Malva's death, given that she is then shown to be talking to Erika again. The other ending was just as good, with the whole deal with Malva and Erika's trauma and mental illnesses.
This game started out as an odd, trippy, and random game, but turned into a beautiful representation of depression and guilt.
