HTML Game Resource Usage Too Large

The Tappy Chicken in Ue4’s example site uses about 500mb while running the game (up to 1.5gb for loading). I went back to 4.9.2 to match the same engine they used to compile this game (since later versions are harder to work on for HTML). But whenever I run the same copy of Tappy Chicken, it always uses 1.5gb while playing. I’ve tried to resize the game’s resolution, canvas size (hopefully doing it right) with no effect. Anyone knows why & how I can reduce the resource usage?

Nevermind, found out I could’ve just changed the heap size when building.
