Hey really cool atmosphere and felt pretty nice to control. The hits and dodge feel good. The heal could be a little more clear when you have the minimum energy to perform a heal, and precisely when the heal has gone off and you can let go of the button.
Like others have said, it was really hard to see anything, once I adjusted my monitor settings it was better. I didn't even realize there *were* spikes in the 2nd room, let alone that I could pogo jump on them.
Really tried to engage with the first boss but gave up after many attempts. I gave it about 10 tries, the iframes on the dodge help, but just found the fight too punishing and inconsistent. Especially in the 2nd phase, the boss's attack comes out so fast / unexpectedly, if you're near the boss at all, a hit seems unavoidable. I love Hollow Knight and other hard games, and I appreciate the challenge, but this was tuned a little too aggressive for me, especially for such an early encounter.
But I'd love to see more of this game if you continue work on it!
