Zoopico by gearfo is a 2D puzzle game made for PICO-8.
In this game, you need to clear the shapes from the board to score points. If any shape reaches the centre square, the game ends. You can hit shapes of the same colour to clear them and hit a shape of a different colour to swap colours. Use power-ups to clear groups of shapes. The wheel clears a whole file. The lightning clears a 3×3 square. The paint blob clears all shapes of the target colour on that side of the screen. Collect 5 springs to clear all shapes from the board.
