Currently, I've been working entirely in 2D, with a 2D map and player representation. I'm having issues however properly creating a grid-based environment. I think the issue is the way I'm casting rays isn't grid-based at all. WebRaycasting is the simplest of the three methods, but the slowest by far. It doesn't really have much advantage over raymarching other than that, except it being much easier to raycast procedurally generated planes. You can use raymarcher distance estimations to calculate intersections as well, ...
