Yes this game contain lot of high polys, this version is still heavy according to it's content.
But the next version who arrive will be even heavier than that.
It's the result of using high quality and detailed assets, high quality textures etc.
It's absolutely not uncommon now to have games of several tens of gigabytes.
Lula's Saga is not a renpy or a 'browser' game.

Search a bit, the area is relatively small, and each place / object where there is potential interact set a small ui with button(s) in the corner.
Owawa give clues when we try to interact.
As I have described in the project page on my site, the purpose is make the less ui possible, no kind of arrows, no such as gps.
As some oldschool adventures games in the 'golden era' we had to search and try many things.
This page is where I explain my plan.
