Yeah there a quite a few objects, but I often make one object multiple objects with the use of directions/animations.
"Every single object has been scaled up 4x in the layout editor" is what I should have said. The sprites were so small that scrolling & movements were just awful. Making everything bigger seemed to be the only work around.
I also make my levels in Tiled, then import them into Construct as separate images and scale up 4x (trying my best to stick to pow2 sizes)..I think the biggest level image I've added is only 45kb though.
