Changes:
Public release 4 (12th feb 2013): mostly polish, fixed gun glitches, nicer font, jump sound fixed, etc.

Public release 3 (5th feb 2013): Vastly improved timekeeping algorithm, marked increase in performance for both lowres and hires versions (practically no slowdown any more)

This is a port of Yeti3D Pro (http://sourceforge.net/projects/yeti3dpro/) by Derek J Evans with various tweaks, bugfixes and improvements, as well as rudimentary gameplay. There are sounds, items that can be picked up, enemies fight back (kinda), etc.
