Thank you for giving the game a chance!
I know that it would greatly benefit from a tutorial, but I was out of time. The most important thing that you seem to not be doing enough is tricking enemies into coming from the side there you have a weapon. That would not only save you from the damage, but give you some energy for killing them.
With the newfound energy it would be much easier to explore, notice the generational patterns for things and adapt.
