I had worked with Jarek for several months prior to the Uragun 1.0 launch, and I must say that he is one of the most dedicated and hardworking folks I have cooperated with. His passion for games is tangible, and his eye for detail is superb. He had a real influence on the final quality of our game, and we owe him a lot! He is one of those guys who embodies great determination and deserves a chance in the game development industry.
