Just played through the demo and had a blast!
I agree with the majority of the criticism here, especially the camera and the moveset. For example I could scale most walls in the game with walljump > thrust which could break lots of challenges.
I think the roll could be cool as a more physics/momentum focused counter part to the thrust. Like you could roll down hill with it, or carry the momentum from a thrust with it.
I'm excited to see what you guys have coming next though! I loved exploring this world and playing with the moveset. I've been working on a 3D beat em up, so I'd be happy to chat more about combat design if you're interested!
