I really liked this one! I do have a couple of notes though:
- I think the walking speed could've been significantly faster. It just feels a little sluggish sometimes
- The ending feels rushed. I get it though, most of the time probably went into making the rest of the game as high-quality as it is
- I wasn't able to find a certain upgrade. Would've appreciated it if the map indicated connections to rooms that you haven't been to
- Combat was kind of clumsy for me. I don't see a good reason for not being able to attack upwards while standing on the ground (or underwater), and there's a bit of start and end lag (preventing you from moving or jumping) for every attack which really threw me off.
- I found it odd that checkpoints don't heal you and you have to pay for health regeneration. It's fine because you get more than enough coins though.
- Here's a tiny nitpick: You don't enter the crouch state if you hold down while in the air before landing
And that's about it. I think the visuals are the strongest part of this, I personally find the art very pretty. Music was nice too. Good job on making this!
Here's my gameplay footage:
