About participating in game jam. 

You can create a game on any game engine(unity, godot, unreal engine, game maker, and others) or just write a game in any programming language. You can create a game alone or as a team. Basic requirements for the game: the graphics should preferably be black and white, the game should use the jam theme, it is desirable that your game can be played in the browser. Pixel graphics can be drawn almost anywhere, for example, even in MS Paint.
