Really enjoyed this one, some feedback:

On my first play, I found no equipment and was generally confusing on how to loot corpses

Bumping to enemies should really auto attack (at least with meelee). Died because of that on my second play through

On my third play through I think game bugged or I enabled a debug thing. I died but I was still able to continue playing. My player sprite was % and enemies was ignoring me but I was able to kill them.
I found maps to a boss but I was not able to go there. Maybe it was because I was dead. Eventually I got bored and restarted game.

In objective, it was saying "find mission objective" in red although I already found the map.

I tried it a couple more times but I died easily to zerglings on one and marines to in other. Game really feels unfair at the beginning unless I am missing something.

I will play it again tomorrow and will try to finish it.
