Music was relaxing, could feel the vibe you were going for. Characters look nice and are well designed. Wall climbing is cool to have, though it's a bit broken in some ways. The guns have some offset compared to where you aim, as well as originating form the camera. The big train/truck passing through is fun. I wish there was a first person mode, though I suppose that would get weird when clinging to a wall.
Looking forward to this since I still like playing TF2, curious how it'll compare.
