I am honestly surprised no one has commented on this demo yet.
I think it has a lot of potential. Several areas in this demo though feel... rough, and do not match up at all with the trailer. One thing I noticed is that the jump feels very short and floaty and the gravity on the Wall Climbing is a little high as well and makes it feel really rough.
The video on this page however looks entirely different so I am not sure if this demo is just a much older version or not. However, other aspects feel insanely polished and I have a lot of hope for this project! I look forward to the next build.
