Paul Simpson of AllMusic gave the album 4 out of 5 stars, commenting that "Edan's fetish for echo and obscure acid rock records is as evident as ever through his mind-bending productions, and Sandman's effortlessly complex lyrics are typically biting as well as insightful."[5] Dean Van Nguyen of Pitchfork gave the album a 6.8 out of 10, writing, "Humble Pi might be thin, but there's enough here to spark hope that this is the origin point of Sandman and Edan's cracked journey, and not the final destination."[7] Nate Patrin of Bandcamp Daily described it as "a short but vivid worldbuilding record, the remnants of old places and past lives still standing in defiance of hyperdevelopment."[6]
"Grim Seasons" was placed at number 2 on Stereogum's "5 Best Songs of the Week" list on August 3, 2018.[9]
