Love the brutalist giger aesthetic but the gameplay side still needs a lot of work.
I assume the movement is the way it is to add to the atmosphere of insignificance in the face of colossal structures of cold stone and rebar but moving like you're in a jar of molasses is too grating. Movement speed is slow, getting the character to start moving takes too long and same goes for climbing. I hope you get the power to jump sooner rather than later.
The gun feels powerful and a pleasure to shoot but could use some sort of recharge indication, at least an audio cue and aiming can be finicky.
As whole the demo looks very promising and I'm looking forward to next builds.
