Looks like itch,io didn't post my comment... So I'm gonna post it again!
Well, this game is sick, starting from the name "Saltsong" (I very appreciate this pun) to the mechanics and visuals. It feels like correct version of both Celeste and Hollow Knight because of combination of Celeste's parkour and Hollow Knight's combat system. Level design is pretty good, movement is fluid. Also this little goofy blobby thingy as a main hero. He is so adorable with his tiny arms and legs! <3
