Thank you man!
I finally watched the video. :) But why on earth are you shooting to everything that comes within range? :D
As a general tip, npcs and journals can provide you valuable informations on how to deal with enemies and deal with things in general.
I noticed that you are playing an outdated version (1.1.3); if you really decide to come back to my game I'd warmly recommend to download the latest one. Even if there is no actual check-point system, the way how a certain item works from version 1.1.4 on does a great difference in terms of starting over.
