I absolutely love the art, music, story and world building in Blasphemous, but I could also not really vibe with the gameplay. Way too much platforming combined with instant kill hazards and janky ledge//ladder grabbing. Also enemy placement that seems deliberately designed to waste your time and prevent you from rushing through areas, even when you backtrack.
I didn't have much issue with the bosses though, at least in the main game. Isidora from the DLC was a fucking pain, though.
