Yes it is! ?
Took me some time to figure out all used keys. I, O and P spawns enemy vehicles, N shoot, M jump and WASD for movement. Not quite sure what this "debris waterfall" (keys t and z tapped rapidly) is, or will be good for (towards the end of the video).
I really hope @masteries will bring this to something playable. Even in this early stage it is already awesome! ??
