This was a really unique experience! I'm not especially good at games, so I can't say much about the controls on tank turning/without, but I can appreciate the aesthetic that they contribute to.
The sound and visual design is really impeccable. I love the ambient music, combat remains unnerving even when you're repeating a level to remedy an accidental death because of the impact sounds, and it just looks amazing.
My only criticism with the camera angles (and this is probably due to my skill level) is that in either control scheme, it's really hard to judge where I'm really attacking, especially when the camera is far away. Sometimes it's easy to run around and get in hits, other times I'm so focused on figuring out where "front" is that I just end up dying. Pressing E twice might be a nice feature if my grasp on space were better.
I've been following this game for a long time, and I really can't wait to see the full thing!
