Blade Chimera, an excellent metroidvania.
Another banger from studio Lady Bug.

Same studio that developed:
• Record of Lodoss War - Deedlit in Wonder Labyrinth.
• Touhou - Luna Nights.

This one's a bit on the easier side, closer to Wonder Labyrinth than Luna Nights.
Lots of interesting mechanics.

At first the game will seem too easy, because regular attacks refill mana, and magic attacks refill health.
But very quickly enemies start hitting harder, so while you can always heal yourself, if you rush in without a plan, you will get crushed.

I'm a couple of hours in, and so far it's excellent demon slaying action, and fun (but forgiving) boss.

An excellent game for the discerning metroidvania fan.
