After a very long break (not really, been busy working and playing guitar), here is finally version 21. This fleshes out the game a little bit, with 3 different rooms, giving a bonus to different resources. Full change log below:

Updated main char gfx
New sound effects
Combat scanner fails less often now
Harder difficulties give more XP
Mute option for music
There are now three different room types, beside the default one. Each of them gives a hefty bonus to finding a particular resource. I will leave it at these for now, but more can be easily added. I find it balanced at the moment, if one has experience with the game.
