Looks amazing! Looks like a 2D game within a 3D environment. Not sure how you've pulled this style off so well. Menu is clean, and combat and grappling is really satisfying. Grappling reminds me of Ghostrunner.
The fact that the weapons are melee seemed unclear at first. Took me a while to realise the grapple can drag enemies towards you. And because of the visuals and the overall pace, it was quite confusing to know where to go sometimes. I know this is a speed running game, but did someone actually manage to beat level 1 in 48 seconds??? I barely managed under 2 minutes! There was the occasionally Unreal fatal crash as well.
