Way too hard, sadly xD
Gave it 3 good tries but restarting again and having to sit through even the sped up dialogue is pretty tedious.
Maybe there's just a way to get health back much later on, but the brain creatures zooming in from off screen feels really unfair when you can only attack in directions you're moving.
The human-sized enemies are probably even worse because they sit inside your character sprite so they are behind you and almost invisible and I'm pretty sure my attacks would just miss them because they're too close?
The visuals, audio and general atmosphere of the game feels great. I'm not sure if there's an end goal but the ghost girl is cute and it's a shame I wanted to spend more time with her floating around beside me.
