Is Don't Starve basically a 2D or a 3D layout which just has a camera which is under a certain angle? I believe it's 3D, still unsure though.
Do you think Construct 2 is capable of such a game? The collisions could be for example just the bottom of trees, bushes... So that movement is possible behind the trees on different layers, that would give the world sort of an effect of the world being 2.5D-ish. =]]
