The friendly mech and fighting on foot combined with the movement options made me think of titanfall and I like having a friendly to fight with. I like the misty atmosphere of the environment. As well as running out of time for a tutorial, I'm assuming you ran out of time for some visuals too since the mech has no animation, many objects are just cubes etc.? As someone else mentioned, I did notice how enemies would run away and disengage after shooting at me a bit, is that a bug or working as intended? But I did like the gunplay, the weapon sounds are satisfying, with the shots sounding impactful and the mechanical noises pleasing. It'd be interesting to see this fleshed out with more polish, enemy types etc.!
