-Mech is pretty darn cool, I like the backpack thing and the transforming feet. No IK on the feet though, oh well.
-Bullets are really bad looking, and I wonder why the bullet shader would get all stretched like that.
-When the camera is on the left side, the gun no longer shoots in the center of the screen(reticle), lol.
-I would like the be able to open my inventory/equipment while in wheel mode(it forces it into leg mode). In real gameplay, it would be nice to move fast while doing such management.
-Shader causes awful aliasing, is this intended? Both the outline and the dotted inline. I think it detracts from your mech model as is.
-I realize you can quickly toggle feet, so you can actually just use the wheels all the time, since you can double toggle and turn instantly instead of doing a big turn radius. Not sure you want that. Besides, I'm not sure the turn radius is even that good of a dilemma compared to slow legs. Maybe you could balance it with better recoil/spread while in leg mode? Or, speeding up the legs.
-The scale seems a bit small, it looks like our mech is only slightly bigger than a man, compared to all the rocks and trees.
-Almost quit before I found the anchor. It's a bit ridiculous, but I like the idea of using a space elevator in place of portals in the Risk of Rain formula. I do wish the glass floor was more obvious, I was worried I would fall through. Too bad I couldn't pick any items up.
Not much to it, but keep up the good work.
