Sokoban-style puzzles are popular, they develop spatial thinking, teach planning ahead, make you think logically. Our Dudu game is similar to sokoban, but slightly improved and slightly more complex. The main character is a red square block that wants to get to a round portal of the same color. But on his way there are blocks of different colors scattered across the field. You need to push them aside to clear the way. You can connect blocks to each other. Shapes of the same color stick to each other when you slide them together. Construct handles to push the group of blocks aside and clear the way to the exit. Each level will have its own set of obstacles and it won't get any easier. The game will make your brain turn around thoroughly and it is very useful and even enjoyable.
