The movement and interactions are quite impressive, the scale of options for climbing and traversing was more than I would have expected.
The sheer number of input combinations was a bit overwhelming. It felt like I was constantly forgetting button combos, or ow to detach from ledges, etc. overall there may not be an issue, but leaning a bit more to contextual options may help new/inexperienced players.
sometimes it was difficult to know what movement options were possible. Some traversal options were very clear (fixed cameras helped in some locations), but others had me trying to wall-run in spots that would not allow it (as far as I could tell). Having visual indicators, such as scrape marks, or more consistent use of the fixed camera may help, but just some ideas.
the combat felt ok, but leaning towards being "slash and run". A block or party would be good to help with situations where the player is backed into a corner. If that option exists, then my mistake, but that probably leans on point #2 with so many button combinations to learn that I just missed it.
controller support didn't seem to work out of the box, some features did, but I couldn't jump or attack on however my setup was configured. Maybe a bad/weird control scheme on my end.
visuals were good for what was present, and the level layout was interesting. I can't say that I'm a fan of the "collapsing building" vibe. To me, it seemed like there were walls or roofs or environmental features missing in some spots. No necessarily bad, but it sometimes didn't feel like I was in a real/inhabited world.

Overall, it seems like a great basis for a good game, and the artwork, visual theme, and animations we're all quite good. I hope the full release is does well for you, and great work on all the effort that it must have taken to get even this far!
