Really cool! I Like the upgrading system and the physics on the walker. Having the resources collected by throwing the axe/pickaxe is very smart and makes resource gathering convenient, though the resources stopped going into my hotbar and so I had to use TAB to see them. You have to manage both your own HP and the HP of the walker while gathering resources and getting rid of Goblins. The goblins are glitchy and really a lot of things are glitchy but that's OK because this game is pretty awesome conceptually. One thing I would have liked to have seen is an FOV slider because the default is way too low for me and was uncomfortable to use. Super neat idea and well done!
