I liked how you streamlined the weapon pickups by removing the ability to cannibalize them for ammo. Exploring was still fun but I can't help but feel it could use just one more element of some kind to making it more engaging. (For example like if you had to find 3-4 switches around the levels to unlock the room the boss was in). Might be a bit too much honestly but that is how I felt.
Thank you for the demo! It was a lot of fun still and I liked the improvements you have made to the core experience!
