I think Blasphemous is a bit more of a Souls game than you give credit for in your list.
2- carefully explore an intricately designed level (usually with lots of shortcuts looping back to save points/safe areas) with minimal to non-existing hand-holding (e.g. no map, no markers, no journal/quest log, no NPCs spelling things out for you plainly, etc.)
Blasphemous has a map, but it's intricately designed with shortcuts looping back, no quest log, and the sidequests are obscure as all hell.
3- survive challenging enemy encounters, traps and ambushes, with often particularly nasty bosses;
Check
4- combat system is stamina-based, methodical, primarily melee-driven, focusing on blocking and/or evading and a "hit and run" style rather than being based on combo streaks or button mashing;
Half check, no stamina, but there's a good bit of needing to block/parry. Mostly melee with a little bit of magic.
7- suffer hardship and punishing loss when you mess up (XP/currency loss on death, sometimes more);
You don't lose your tears, but you do build up guilt that you need to reclaim from where you died.
Plus the bile jars are essentially estus flasks/blood viles.
