It's an interesting game, never had a key bat mechanic before in a game; and it definitely has potential for really cool puzzles.
For me personally, a chunk of the time the jumps felt impossible or very unlikely I'd make them. A few key shots in and I couldn't get the jump down.
The movement feels glidey, like the character is walking on ice. The deceleration doesn't feel high enough. I didn't face any precise platforming which made this more of an issue of moving around than overcoming obstacles.
The character collider also looks like it's a little too big; the player stands off the ground by a pixel or two.
You can also trigger narrative more than once if you go back. I found this out after getting the key bat and wondering if I could open the chest at the start. Then retriggered multiple NPC narratives.
The music is really good and fitting; absolutely enjoyed it! The art is also very nice and has some character to it which is great. I'm not in love with the text color and textbox design; but it passes through.
