Played the full demo, since it was short I'll try to focus only in combat core mechanic.
Overall I think the combat wasn't interesting, even as I lost a couple times, melee for the most part was bad unless I used it in corners so i tried to shoot enemies whenever I could, and the gun mechanic was kinda boring
About resources, having to manage bullets loaded and health was ok, I had to take some decisions based on it, meanwhile sprint was just a bar that I depleted trying to run from place to place as i defeated new enemies.
The boss seemed to bug out being unable to attack me
