So in the easy allies impressions above. He mentioned a couple things I thought was thread worthy
-The e3 demo, like many others, was made for the sake of quick run throughs and hands on sessions at e3, the same level in the full game has many more of the metroidvania elements
-Difficulty in the demo was turned down and will be "much more difficult" in the full thing.
This was something speculated about but good to have confirmation.
