1930 is a survival logic puzzle game set in a pixelated black and white world where creepy anthropomorphic square balloons stalk innocent circles. The player must save the circles from this harassment by destroying the squares using a variety of methods. Although not a Red Ball title, 1930 has a similar premise of geometric shapes having difficulty living in the same world because the squares behave in evil ways.
The game presents the player with perfect and semi-perfect simultaneous or mirror movements of the squares and circles. The circles want nothing more than to be left alone. Yet the squares stay close to them and match their every move.
Each of the 24 stages of the game features a white portal doorway that one or more circles can use to flee. That said, they can only leave a level if the player has helped them destroy every square in it. If a level doesn't have a square in it, then the player must complete a task, such as directing one or more circles around other types of threats. Common obstacles include ground-level spikes and creatures covered in spikes.
1930 provides the player with several tricks that can help circles escape. They can use small spinning portals that look like white flower blossoms to push squares toward danger or help circles escape squares. The game also offers a long jump option sometimes and allows circles to merge together to form one circle that can more easily escape harm.
