This is a special one, what a beautiful presentation!
My only critique is the ending I got on the second playthrough. I chose not to pick up the ant, but said I regretted it. Then I interacted with the student and interacted with the familiar face, asking for advice and having positive experiences.
Then the spirit told me I wasted my time, was CONSUMED BY RAGE and would spend forever in purgatory, not sure if I quite why those choices lead to that outcome when the previous playthrough was so much more pleasant (even though I didn't go talk to the person but chose to pick up the ant the first time) lol.
In any case, it's a wonderful game, love the haunting music and visuals!! Awesome job!
