Just started playing Boneworks, had a fairly long session because I was enjoying myself, got to some weird blue zombie-like enemies and a huge drop down into a sewer type level, where i've left it for now.

So far I am enjoying the game very much, once I learned how to correctly mantle things it became much easier to get around but I am finding the "gunplay" difficult, I am playing on an Oculus Quest, which I hear does not have the best screen quality and I find it extremely difficult to see fine enough detail to use my ironsights correctly. This combined with not knowing how to check my health has made combat very frustrating against those rolling ball things. 
Does anyone have hints for this? Is it just my headset or can I improve this situation?
