Nice game!
Demo is short and i wish there were more weapons to try. Actually how many are there? I found the plasma gun and some shotgun shells, but no shotgun.
The SMG also feels a bit weird: I tried using the scope to head shot the first enemies from afar, but i don't think head shots do more damage then regular hits. So because of the recoil i didn't use the scope at all after this and just hip fired everything to death.
The visual style and the audio are pretty coherent, has soul and doesn't feel cheap. Had no bugs for the playthrough.
Seems like a solid foundation that needs content and a little more oomph to the weapons. Hopefully explosives too.
