It's a really weird choice that you decided to change the camera, I think that with the proper adjustments a third person camera could work fine. You are kinda using a camera that feels more appropriate for a 2D game but your game is clearly 3D, with ledges, ramps and pits which also collide with the fact that there is no jump button (wasn't there one in the last demo?)
Your game felt like it was going in a direction that would end up with exploration and interaction with all kinds of stuff but it's hard to explore comfortably with a camera that doesn't allow much free will.
I'd like to see the reasoning behind this change because I feel it only damages the game.
Besides that I don't have much to say, it was very short with an abrupt ending but with everything fleshed out it could be nice and comfy.
