Now I have a demo version CD that I kept since childhood and bought this full version from GOG. The demo version of this game works flawlessly on modern computer. However GOG version is nowhere close to the original game... - The enemy AI after first attack starts randomly running into wall making the combat too easy. - The dionsaur boss fight was completely ruined as it was a very long, tiring and boring shooting at a boss which spent 10 minutes running into wall instead of attacking me. + The game maps, puzzles, everything unrelated to combat seems to work fine. I really like this game, but not from GOG vendor. This was my very first purchase on GOG and I would have rather paid a higher price for fully functional original product than this.
