So first thoughts.
From the early days it greatly improved. The tutorial and the ability to skip and summon it again is very useful and it's not annoying. I like what is the exploration going for, but I see bit of things that may get in the way of the player.
For instance, It happened commonly that I entered an area with no gunbox dropping out of the mech. Also having one gun for start can be quite frustrating. If it's supposed to be a little tricky, then I recommend to make it so that the player sticks to it, make it feel good playing. For instance I would Highly recommend adding sounds. Music or ambience, that's your choice.
I'll be happy to contribute more feedback. Good job.
Stay safe and be healthy!
