This feels pretty good so far! There's some odd glitchiness surrounding Granite Act 2--in my first playthrough, I spawned pretty close to the end of the level for some reason, and in the second playthrough, it was called Sunset Gate Act 2 in the title card--but otherwise things seemed to work as intended. Visually Sunset Gate is quite nice, though I think you could play with the palette some more... it's all pretty basic green and brown right now, and this is a PC game, you don't actually need to worry about using a standard sixteen color palette or whatever. It could definitely use more to DO right now, too, especially with the gloriously gimmicky Golden Capital Zone to compare act 2 to. Right now you have cool flower animations and basically nothing else to make the zone interesting. Granite is very good, by contrast.
