A joy to run through!
Gameplay is great, with tight controls and a nice level of challenge. Would love the option to skip the intro cutscene and dive straight back into the action, although given how short it was this wasn't a big issue :). The different powerups were great fun, with my favourite being the dash as flinging myself across the room to behead guards just felt amazing.
I loved the character models, and as GamePasta has pointed out the arm swinging melee attack is fantastic.
The improvements seem really good. The game just feels much juicier than the prejam version with the updates to audio (particularly the opening and the gunshots, the new filter and the defenseless scientists (I murdered as many as I could find). Environments feel more fleshed out - the boxes and wall panels add a surprising amount, and the skybox in the exterior area looks great.
