Very nice ending animation.
The game is fun. In the context the environments look great and are quite detailed. Movement feels alright, not perfect but fine. I really like the music when inside the building while the music outdoor fits the gigantic environment. I love the verticality, that you get to go there and that there are a few dead ends as well there, the environment is super fun to interact with, I really enjoyed solving the game. It is satisfying to reach the summit.
I think the commands are perfectly fine yet not super intuitive at first. It's not completely evident you got the jumping ability and holding Space and pressing W is not super intuitive at first either even knowing Space is used to jump. The first times I grabbed a ledge I always kept Space pressed afterwards and then jumped into the void instead of moving up so judging only by my experience it should simply move up instead of jumping when Space is kept pressed and you move up while holding a ledge.
I wish there were combat of course, I'm sure you do to.
As is the game is already a cool game I enjoyed playing to the end and I'd be super excited to explore the same kind of levels but with combat too.
