Very fun game - and this is coming from someone who is not the biggest fan of Metroidvanias. It's literally this one and, like, Hollow Knight?
The only issue I have is that the later levels are very unfun to play through, with a bunch of hit-sponge enemies and bosses thrown in, and one level that is just constantly draining your health - which is never fun.
Overall though, it was a beautiful experience and I'm glad I stuck it out.
