This feels like a complete game, it's amazing. I appreciate the time you spent on the level design. And the start menu immediately establishes the theme, so good work there.
A few notes:
- You mentioned that you wanted to make the platforming challenging like Hollow Knight. I understand what you mean, but I would appreciate a little deceleration on the movement so that it wasn't too sensitive and harder to land jumps. In HK, there's a slight delay between releasing input and movement stopping, so it just feels a little more fluid. I don't think it's lag, either.
- I experienced lateral movement is disabled while in the air if you are also pressing up. Not sure if this was intentional.
- I notice the enemies freeze when they are off screen. In some situations, that means an enemy jumps in the air and doesn't reappear until I look up there haha
I like the challenge of navigating your way around and remembering the locations you have to revisit. Very good exploration feel, and very satisfying to build up your sense of the world. It was very immersive!
