So. umm... Apart from the fact that I found a dead body in what otherwise looked like a normal game (I know that that was probably intended, but I would recommend adding at least a warning, since there are people sensitive to that), it is sort of odd that the game just sort of … ends once you find it. it doesn't take you to the menus or anything . I don't know to feel about that.
Also, that part where you had to solve a puzzle like very quick before the Roomba dies was also like really thigh and punishing. I would recommend adding a conveyor belt or something that slowed the Roomba down. And maybe make the blocks visible so one at least has a semblance of knowlegde of what to do.
Otherwise, cool game!
