Yeah, I unfortunately didn't like the movement engine. It felt like you were moving through jell-o rather than time moving base don your speed and getting onto ledges was more than a bit fiddly too. Hitboxes for the pickups could have been larger too or at least the timer a little less aggressive
That's not to say there is nothing there. The individual parts of the movement engine could be cool and you sometimes do see the potential shining through, but overall I don't think it quite comes together.
Sorry to say, but I didn't enjoy it despite wanting to.
