I just finished this game. It’s less than an hour long. (Or should be, but the 2D parts are poorly programmed. Near the end I just switched off the spikes rather than continue to fight with the controls.)
The game is stranger than I expected, sometimes going for absurd or morbid humor while relating the story. I thought it might be similar to The Pedestrian but it’s more of a walking simulator than a puzzle game, despite the 2D platformer sections.
