I enjoyed and played through to the end. I think you balanced it well, although I was able to finish it on my first playthrough, I might just be a god gamer though, who knows?
The graphics were great, but I wish there was a little more SFX and maybe different or longer looping music.
I think there is a fun base here, and would love to see a mechanic that allows you to drill into rocks, or something else then simply dodging and evading.
