Hi there, it was really fun watching you play the game!
The durability feedback issue is something I'm still thinking about how to design, while for the damage I will probably use a cutscene to make the player understand that the character just received damage, so to have something organic that explains the thing.
Regarding more health pools: the demo is a collection of rooms that will be on the final map, but positioned way differently. As I'm trying for a Zeldaesque open-world feel there will be much more health/save points that the player can access in multiple ways.
Thanks again for trying Sliding Hero!
