A contemplative story, with a lot left unsaid and, at the same time, a kind of sense of security. I think this mixture of strangeness and closeness that one can feel towards a parent, especially a father (who is rarely emotionally equipped to communicate his feelings) is really right and touched me a lot.
All I got at the end was a blank screen, without the game telling me that I'd reached the end - but as I played on mobile (and more precisely on safari), that may just be a compatibility problem.
