Last week a group of courageous Estonian people went to the Spelkollektivet Halloween GameJam. It is a one-week of life in most pro game dev places in Europe.
Two games were made:

Comment from one of the participants:
So what about Spelkollektivet and Jam. Since I had little understanding of the process of creating games up to this event, and from my experience I only had a theoretical vision of how the game would look like. And it turned out that I had to learn quickly and immediately put my knowledge into practice. So I realized what it’s like to be a game developer who crunches 24/7. It was a real challenge for me, as a person who loves games very much and would like to understand how this art is created.
All these 4 days I was completely immersed in the process of work and at some point, I got so deep that I lost track of time. Moreover, due to the fact that I was very worried about what would happen, I got micro burnout when I accidentally deleted all my prefabs. An unforgettable feeling.
However, despite this, I redid half of the levels and managed to bring the game at least to the stage of a playable alpha for presentation.
The atmosphere in Spelkollektivet was so wonderful that I had no desire to stop polishing my game. People are extremely friendly, and responsive, there is always someone to turn to. I strongly advise everyone who is just thinking or has already decided to start their way into the gaming industry.
