The Ice Temple is the third adventure in Oslo Albet's Fireboy and Watergirl series of co-op puzzle platformers. The two heroes return with their familiar weaknesses, Fireboy cannot touch water and Watergirl cannot touch fire, but this time the temple is covered in ice and snow, and that changes how every level plays.
Ice makes the floors slippery, so stopping exactly where you want takes practice, and a slide in the wrong direction can carry a character straight into the wrong pool. Snow and frozen surfaces sit alongside the levers, buttons and moving platforms the series is known for, so the puzzles ask for careful movement as much as quick thinking.
Guide both characters through each level, collect the red gems with Fireboy and the blue gems with Watergirl, and bring both of them to their matching exit doors. Green goo is deadly to both. You can play with a friend, one character each, or control both yourself.
